There is still a missing piece in the 040 support--that's the
virtual-to-physical address lookup function.  The macs have a
lot of variation in the way that memory is laid out and we try
to take a mostly free ride in setting that up by reading what
the MacOS set up for the MMU (the requirement for 32-bit addressing
and hence Mode32 are derived from this).  This is largely for the
support of the IIci and IIsi.  A number of systems don't need this
code, but a number of them do.

I seem to remember at least two people had started to do this work...
