Is there a limit to the number of modules one can load at boot time?  I
have a list of modules to load in loader.conf, I see loader load them, but
then the kernel never mentions them in startup.

loader.conf:
userconfig_script_load="YES"    # Load userconfig settings
### Modules
# Network
if_dc_load="YES"        # NetGear FA310TX
if_xl_load="YES"        # 3Com 3c900B-TPO
if_ppp_load="YES"       # PPP
# Filesystems
msdos_load="YES"        # FAT
nfs_load="YES"          # Network Filesystem
procfs_load="YES"       # Process filesystem
# Sound
snd_emu10k1_load="YES"  # EMU10K1 driver
# Misc.
agp_load="YES"          # Accelerated Graphics Port
usb_load="YES"          # Universal Serial Bus
vn_load="YES"           # Virtual Node support

When I boot, I see them all loaded before kernel is started.  But then in
the bootup messages:

FreeBSD 4.3-BETA #1: Mon Mar 19 22:15:45 CST 2001

Notice it loads miibus.ko, which I don't even specify in loader.conf?  This
shows that loader is reading all the modules and adding their dependancies,
but why isn't the kernel getting them all?
