The 601 is a different-enough chip to make it a little harder. My
understanding of the 601 is that it was a "time to market" sort of
thing, and that the differences between the 601 to 603 or 604 are
analogous to the differences between the 68020 and the 68040 or 68060.

The NuBus Powermacs are not OFW. But, you can re-use a large chunk of
the Hard Bits (locore, pmap, trap handling) from NetBSD/powerpc and
get code for the missing bits from Mach. It's very unlikely that much
of the code you need will actually be in the MkLinux server. The
u-kernel is what talks to the hardware, really.
