  Certainly.  I looked at the mac68k pmap_bootstrap.c, and it would be a 
little messy for that port.  The value for physmem is set near the end of 
pmap_bootstrap(), well after the kernel page tables have been initialized. 
I'm not clear on how physmem gets calculated on the mac68k, but I would 
think a rough aproximation on the size of memory is all that would be 
needed.  The other m68k ports other than the amiga, atari, and sun3 appear 
to have physmem set before pmap_bootstrap() is called, so that should be 
an easy fix for those.
