I have wondered about such numbers myself.  My personal opinion for
some time is that MiNT should drop all support for CPU's below the 68030.
However, I do not know how that would effect upgraded machines.
Are there 030 upgrades and if so do they have proper MMU's on board?
I also do not know anyone who actually uses MiNT on anything less than
an 030 as it is.

If that is your honest assessment then split/branch the CVS and do whatever
you wish since it's dead.  I've heard estimates there is only 3 active users
here anyway.  ;-)

Some, not all.
