It (alas) has not fixed the problem for me. I've rebuilt trwice from scratch
and with a few different options. I'm now fiddling with the amount of symbol
table space for DDB to see if that can be made to shift things around enough.
I enclose my config file for your amusement.

#
#
# Priapus - the watchdog that has to stay up all the time.
#
#
# This directive is mandatory; it defines the architecture to be
# configured for; in this case, the 386 family. You must also specify
# at least one CPU (the one you intend to run on); deleting the
# specification for CPUs you don't need to use may make parts of the
# system run faster
#
machine "i386"
cpu "I486_CPU"
#cpu "I586_CPU" # out until transient problem fixed
#
# This is the ``identification'' of the kernel. Usually this should
# be the same as the name of your kernel.
#
ident priapus
#
# The `maxusers' parameter controls the static sizing of a number of
# internal system tables by a complicated formula defined in param.c.
#
maxusers 20
#
# Space savers
#
#options "NMBCLUSTERS=128"
#options "BUFPAGES=128" # 512k for buffers
#
# A math emulator is mandatory if you wish to run on hardware which
# does not have a floating-point processor. Pick either the original,
# bogus (but freely-distributable) math emulator, or a much more
# fully-featured but GPL-licensed emulator taken from Linux.
#
#options MATH_EMULATE #Support for x87 emulation
#options GPL_MATH_EMULATE #Support for x87 emualtion via
#new math emulator
#
# This directive defines a number of things:
# - The compiled kernel is to be called `kernel'
# - The root filesystem might be on partition wd0a
# - The kernel can swap on wd0b and wd1b, defaulting to the former
# - Crash dumps will be written to wd0b, if possible
#
config kernel root on wd0
#####################################################################
# COMPATIBILITY OPTIONS
#
# Implement system calls compatible with 4.3BSD and older versions of
# FreeBSD.
#
options "COMPAT_43"
#
# Allow user-mode programs to manipulat their local descriptor tables.
# This option is required for the WINE Windows(tm) emulator, and is
# not used by anything else (that we know of).
#
options USER_LDT #allow user-level control of i386 ldt
#
# These three options provide support for System V Interface
# Definition-style interprocess communication, in the form of shared
# memory, semaphores, and message queues, respectively.
#
options SYSVSHM
options SYSVSEM
options SYSVMSG
#####################################################################
# DEBUGGING OPTIONS
#
# This line enables the kernel debugger, DDB, and the line following
# allocates extra space for a copy of the debugger symbol table which
# is stored in the initialized data area of the kernel. If you change
# the latter option, remove db_aout.o before compiling.
#
options DDB #Kernel debugger
#options "SYMTAB_SPACE=113498" #This kernel needs LOTS of symtable
#
# KTRACE enables the system-call tracing facility ktrace(2).
#
options KTRACE #kernel tracing
#
# The DIAGNOSTIC option is used in a number of source files to enable
# extra sanity checking of internal structures. This support is not
# enabled by default because of the extra time it would take to check
# for these conditions, which can only occur as a result of
# programming errors.
#
#options DIAGNOSTIC
#####################################################################
# NETWORKING OPTIONS
#
# Protocol families:
# Only the INET (Internet) family is officially supported in FreeBSD.
# Source code for the NS (Xerox Network Service), ISO (OSI), and
# CCITT (X.25) families is provided for amusement value, although we
# try to ensure that it actually compiles.
#
options INET #Internet communications protocols
#options ISO
#options CCITT #X.25 network layer
#options NS #Xerox NS communications protocols
#options TPIP #ISO TP class 4 over IP
#options TPCONS #ISO TP class 0 over X.25
#
# Network interfaces:
# The `loop' pseudo-device is mandatory when networking is enabled.
# The `ether' pseudo-device provides generic code to handle
# Ethernets; it is mandatory when a Ethernet device driver is
# configured.
# The `sl' pseudo-device implements the Serial Line IP (SLIP) service.
# The `ppp' pseudo-device implements the Point-to-Point Protocol.
# The `bpfilter' pseudo-device enables the Berkeley Packet Filter. Be
# aware of the legal and administrative consequences of enabling this
# option. The number of devices determines the maximum number of
# simultaneous BPF clients programs runnable.
#
pseudo-device ether #Generic Ethernet
pseudo-device loop #Network loop back device
pseudo-device sl 2 #Serial Line IP
#pseudo-device ppp 2 #Point-to-point protocol
pseudo-device bpfilter 4 #Berkeley packet filter
pseudo-device tun 1 # Tunnel device
pseudo-device vn # Vnode driver (turns file into device)
pseudo-device disc # Discard device
#options NSIP #XNS over IP
#options EON #ISO CLNP over IP
#options LLC #X.25 link layer for Ethernets
#options HDLC #X.25 link layer for serial lines
#
# Internet family options:
#
# TCP_COMPAT_42 causes the TCP code to emulate certain bugs present in
# 4.2BSD. This option should not be used unless you have a 4.2BSD
# machine and TCP connections fail.
#
# GATEWAY allows the machine to forward packets, and also configures
# larger static sizes of a number of system tables.
#
# MROUTING enables the kernel multicast packet forwarder, which works
# with mrouted(8).
#
# IPFIREWALL enables support for IP firewall construction, in
# conjunction with the `ipfw' program. IPFIREWALL_VERBOSE does
# the obvious thing.
#
# ARP_PROXYALL enables global proxy ARP. Beware! This can burn
# your house down! See netinet/if_ether.c for the gory details.
# (Eventually there will be a better management interface.)
#
options "TCP_COMPAT_42" #emulate 4.2BSD TCP bugs
#options GATEWAY #internetwork gateway
options MROUTING # Multicast routing
#options IPFIREWALL #firewall
#options IPFIREWALL_VERBOSE #print information about
# dropped packets
#options ARP_PROXYALL # global proxy ARP
#####################################################################
# FILESYSTEM OPTIONS
#
# Only the root, /usr, and /tmp filesystems need be statically
# compiled; everything else will be automatically loaded at mount
# time. (Exception: the UFS family---FFS, MFS, and LFS---cannot
# currently be demand-loaded.) Some people still prefer to statically
# compile other filesystems as well.
#
# NB: The LFS, PORTAL, and UNION filesystems are known to be buggy,
# and WILL panic your system if you attempt to do anything with them.
# They are included here as an incentive for some enterprising soul to
# sit down and fix them.
#
# One of these is mandatory:
options FFS #Fast filesystem
options NFS #Network File System
# The rest are optional:
#options "CD9660" #ISO 9660 filesystem
#options FDESC #File descriptor filesystem
#options KERNFS #Kernel filesystem
#options LFS #Log filesystem
options MFS #Memory File System
#options MSDOSFS #MS DOS File System
#options NULLFS #NULL filesystem
#options PORTAL #Portal filesystem
options PROCFS #Process filesystem
#options UMAPFS #UID map filesystem
#options UNION #Union filesystem
options DEVFS #devices filesystem
#
# Disk quotas are supported when this option is enabled. If you
# change the value of this option, you must do a `make clean' in your
# kernel compile directory in order to get a working kernel.
#
#options QUOTA #enable disk quotas

# MISCELLANEOUS DEVICES AND OPTIONS
#
# Of these, only the `log' device is truly mandatory. The `pty'

# ISA and EISA devices:
# Currently there is no separate support for EISA. There should be.
# Micro Channel is not supported at all.
#
# Mandatory ISA devices: isa, sc, npx
#
controller isa0
#
# Options for `isa':
#
# ALLOW_CONFLICT_IOADDR suppresses the I/O address conflict checks, so
# that the PS/2 mouse driver doesn't conflict with the console driver.
#
# ALLOW_CONFLICT_IRQ suppresses the interrupt line conflict checks, so
# that multiple devices can share the same IRQ, provided that the
# hardware supports it (it usually doesn't).
#
# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
# than 16 megabytes of memory. It doesn't hurt on other machines.
# Some broken EISA and VLB hardware may need this, too.
device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr
#
# Options for `sc':
#
# NCONS specifies the number of virtual consoles. Specification of
# this value is mandatory. Due to a compiler bug, when compiling with
# GCC 2.6.0 this option must be a power of two.
#
# FAT_CURSOR specifies the use of a large block cursor rather than the
# hardware default underline.
#
# HARDFONTS allows the driver to load an ISO-8859-1 font to replace
