To expand on my previous message, I understand this part of the problem
pretty well at this point.  While I did write code to get the physical
address corresponding to a logical/virtual address (trivial, really), by
the time NetBSD tries to figure out how memory is mapped, the 040 MMU has
been disabled.   Leaving it enabled has its own set of problems. :-(

I haven't come up with a reasonable solution for this yet.
