i dont know if this is related, but i've had this experience:

1. freebsd notebook dies/crashes due to power failure (my bad)

2. a reboot of the notebook comes up fine with the exception of a totally 
missing bge0 device, Broadcom BCM5751M Gigabit Ethernet. nothing i did 
could find the device including pciconf.

3. reboots with shutdown -r didnt still showed a missing device when the 
notebook rebooted.

4. shutting down the notebook using ACPI (acpiconf -s 5) and a subsequent 
reboot brought the device back to life as if nothing had happenned previously.

i wonder if there's something in ACPI which caused this behaviour, and 
could be responsible for the symptoms you're seeing. admittedly, this is a 
shot in the dark as till today i've no clue why my bge0 device disappeared 
for a short period of time. agents mulder and scully are investigating.
