	NetBSD does not currently support the 601 CPU, though apparently
	that is not a massive job (its used in a number of early powermacs
	which is why its been brought up before :). The existing MCA bus
	support should be reasonably MI (I'd expect a few tweaks might
	be needed in the MI code, but nothing serious - hopefully :),
	and the prep port might provide a good starting point.
