I would have attached the dmesg originally but it didn't even show the pcm
probe at all... and there was nothing strange in it (I did look for errors).
My current kernel has got voxware in unfortunately... and I'm currently
building world (again) d8/ I can rebuild a kernel afterwards with pcm=20
compiled in and send that, but, that won't be for a few hours yet...
It's 1:30 am here right now and my kids will be waking me up
for fathers day nice and early so I can't pull a dawner tonight.
Here's my kernel config and dmesg from a working kernel.
The changes I've made other than to comment out the pnp controller,
is to add the
options CPU_FASTER_5X86_FPU
I'm going to remove that next kernel build as well to see if that makes
a difference.
I'll forward you a non-working dmesg tomorrow my time I guess unless
something comes to light before then.

# SCSI DEVICES
# SCSI DEVICE CONFIGURATION
# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device `type' drivers, and the low-level host-adapter
# device drivers. The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
# that a given bus, target, and LUN always come on line as the same
# device unit. In earlier versions the unit numbers were assigned
# in the order that the devices were probed on the SCSI bus. This
# means that if you removed a disk drive, you may have had to rewrite
# your /etc/fstab file, and also that you had to be careful when adding
# a new disk as it may have been probed earlier and moved your device
# configuration around.
# This old behavior is maintained as the default behavior. The unit
# assignment begins with the first non-wired down unit for a device
# type. For example, if you wire a disk as "sd3" then the first
# non-wired disk will be assigned sd4.
# The syntax for wiring down devices is:
# controller scbus0 at ahc0 # Single bus device
# controller scbus1 at ahc1 bus 0 # Single bus device
# controller scbus3 at ahc2 bus 0 # Twin bus device
# controller scbus2 at ahc2 bus 1 # Twin bus device
# disk da0 at scbus0 target 0 unit 0
# disk sd1 at scbus3 target 1
# disk sd2 at scbus2 target 3
# tape st1 at scbus1 target 6
# device cd0 at scbus?
# "units" (SCSI logical unit number) that are not specified are
# treated as if specified as LUN 0.
# All SCSI devices allocate as many units as are required.
# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
# configuration and doesn't have to be explicitly configured.

# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
# Automatic EOI is documented not to work for for the slave with the
# original i8259A, but it works for some clones and some integrated
# versions.
#
# MAXMEM specifies the amount of RAM on the machine; if this is not
# specified, FreeBSD will first read the amount of memory from the CMOS
# RAM, so the amount of memory will initially be limited to 64MB or 16MB
# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
# then attempt to detect the installed amount of RAM. If this probe
# fails to detect >64MB RAM you will have to use the MAXMEM option.
# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
# be 131072 (128 * 1024).
#
# TUNE_1542 enables the automatic ISA bus speed selection for the
# Adaptec 1542 boards. Does not work for all boards, use it with caution.
#
# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to
# reset the CPU for reboot. This is needed on some systems with broken
# keyboard controllers.

# `iosiz' for npx0:
# This can be used instead of the MAXMEM option to set the memory size. If

#
# The flags fields are used to enable the multi-sector I/O and
# the 32BIT I/O modes. The flags may be used in either the controller
# definition or in the individual disk definitions. The controller
# definition is supported for the boot configuration stuff.
#
# Each drive has a 16 bit flags value defined:
# The low 8 bits are the maximum value for the multi-sector I/O,
# where 0xff defaults to the maximum that the drive can handle.
# The high bit of the 16 bit flags (0x8000) allows probing for
# 32 bit transfers.
#
# The flags field for the drives can be specified in the controller
# specification with the low 16 bits for drive 0, and the high 16 bits
# for drive 1.
# e.g.:
#controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0x00ff8004 vector w=
dintr
#
# specifies that drive 0 will be allowed to probe for 32 bit transfers and
# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
# allowed to probe for 32 bit transfers, but will allow multi-sector
# transfers up to the maximum that the drive supports.
