The HPET issue was actually because the seabios already contained an
HPET definition and mac os X didn't know quite what to do with a CPU
with two APICs :)

I removed the spare HPET def, and it doesn't moan about unsupported
hardware anymore.

However AppleIntelCPUPowerManagement dies with a bad opcode error and
no useful information on why.. I get the impression that worked OK
unmodified with your original suite of patches? Obviously if you
disable the KEXT its no longer a problem, but it would be nice not to
have to.

10.6.5 still doesn't start the GUI though, and I've still no idea why yet.

Also, mac os x reports that an emulated e1000 device has an all-zero
MAC address. I'm going to look into this first since the rtl8139 only
has 32 bit drivers it seems.
