The kernel reprograms the page tables at boot time, so the only reason
to have the MMU configured is to allow the machdep.c:get_mapping() call
from pmap_bootstrap.c:bootstrap_mac68k() to work.  Can you boot at all
with the MMU disabled?

In more answer to your question, it looks like machdep.c:get_physical()
will work with either 8K or 4K page size.

When you are running with your accelerator configured, does it show that
you have a 68040 running?  Does NetBSD know that you have a 68040, or
does it still think that you have an '030?
