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.
