That's a good one. Of course that's a very effective way of writing BitBlt
on a 68020 if you explicitly flush the I-cache. Henry Spencer has claimed (and
I believe him) that using this technique you can get 100% data bus utilisation
with bitblt on a 68020. Of course on a 68000 you should probably just use the
blitter. :->

Anyway, I've observed a positive correlation between "manic assembler program"
and "does not work on the 68030". Assembly for critical code is one thing, but
writing the whole thing in assembly is pure machismo.
