There's progress! With your latest patch using brgphy.c, if_bge.c, and
if_bgereg.h from head I'm now seeing the bge0 interface. Unfortunately, the
moment I try to configure it the box locks up completely; it won't even toggle
the caps lock LED.

Booting single user and running ifconfig shows:

bge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
	ether a8:20:66:11:3b:d6
	media: Ethernet autoselect (1000baseT <full-duplex>)
	status: active

I did a verbose boot; here's the part that seems to be relevant to bge0:

bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x57766001> mem

bge0: bpf attached
bge0: Ethernet address: a8:20:66:11:3b:d6
ioapic0: routing intpin 16 (PCI IRQ 16) to lapic 0 vector 61

I greatly appreciate your efforts. I'm sorry for the delay getting back with
you, but we had a busy Thanksgiving weekend.

Thank you!
