	We have a cross/powerpc-netbsd package in pkgsrc - there are notes
	on using this to compile a bebox kernel (which is pretty much the
	same) at:

	It would probably be a little more effort to do it on FreeBSD,
	YMMV.  I've always been a big fan of being able to have the same
	OS across different hardware :)

	The best approach would be to take the nubus and similar code from
	the mac68k port, make it Machine Independent, and conditionally
	include it on the macppc port. There are MI drivers for virtually
	all the other busses used in the various NetBSD ports in /sys/dev
	and many MI chipset drivers in /sys/dev/ic.

	I'm sure some mac68k people may have helpful suggestions to make
	on this :)
