But with a PowerPC MMU, which is the important point.

Watch out for instructions that try to access HID0, like flushing the
caches, which is very different on 601. I remember seeing various places
(and suggesting some fixes) where accesses to HID0 were not protected with
a check of the processor type. But it was several months ago and I don't
know if all such problems have been fixed now. 

This was my $0.02 tip of the day.
