All you need for a macppc kernel is arch/macppc and arch/powerpc -
plenty of files were moved, added or deleted so you better clean out
OBJ and such.

Hmm, no such problems here.

Not without some hacking - macppc relies on the firmware to tell it
what's the console.
I found something very strange - I get gem timeouts with the snapper
driver removed but it works fine when snapper attaches. No idea why
exactly, the driver doesn't touch any of uninorth's power or clock
enable registers as far as I can see, only enables the i2s clock which
is part of mac-io and shouldn't have anything to do with gem. Will
