But this probably won't help X much.  The X server and most apps don't
do that much floating point.

Hmmm, the work I'm doing on the 3/80 might be able to be tweaked to
recognise a '030.  I wonder if the Sun MMU can be disabled?  I'll have
to check the arch manual.

There is no difference between gcc's -m68020 and -m68030.  I believe
that there are no differences in the user instruction set between the
two parts.
