I suspect that yamt's question was more specific: Which MMUs are
in use in the news68k and hp300 systems on which Chuck is currently
testing?

The 68851 and 68030 MMUs are quite similar, as I recall, and the
68040 adds some twists.  At least one mac68k that Chuck is using
is a Q950, which uses a 68040.  If the news68k and hp300 systems
are also using a 68040, it reduces the places where a bug might lie.

At least, that's my reading.  I'm sure that yamt can correct me if
I'm wrong.
