Booting a 2nd rev 12" powerbook (1Ghz)

[peter at larkowski.net]

Hi all.  I'm trying get freebsd onto my 12" powerbook (2nd rev, 1Ghz,
airport extreme, mini-dvi, etc, etc) and the kernel from
http://people.freebsd.org/~grehan/kernel.syscons crashes with or without
syscons and regardless of the presence of a usb keyboard.  Here's the tail
end of the dmesg:

.....
pci1: <network> at device 18.0 (no driver attached)
macio0: <Intrepid I/O Controller> mem 0x80000000-0x8007ffff at device 23.0

At this point, if I am in syscons, I have no keyboard any longer, so I
hold the power button and return to OSX, but if I disable syscons, I can
poke around in the debugger on either keyboard (usb or builtin)  Any
thoughts?
