I believe that Transformer has problems with illegal instructions on a
68020 or '030.  I think there is a patch out there that goes through the 
xecutable and replaces the illegal instructions with the legal replacement.

Also, you would have to disable the cache on the 68030 chip.

Then, if you disable all memory except 512K of chip ram, it might work.

Only two things might ruin it - if the Transformer uses the emtpty 8-bits
of 24-bit addresses to store data (I don't think Commodore would do this?)
then it is pretty hopeless, since the 68030 takes the whole 32-bits as the
address.  The other problem would be if the Transformer goes directly to
the hardware to get extra speed.  The 3000 is so different in the hardware
that anything that goes to hardware on the 500/1000/2000 wouldn't work on
the 3000.
