Don't bet on it.  And I was surprised, too.  But Marble Madness, from 
Electronic "We develop on PC-ATs" Arts, of all things, runs BETTER on a
68020 system, in exactly the way you mention above.  It's apparently
synced to the video frame rate, not the CPU speed, and the main effect of
running it on a FAST 68020 based system is that the mouse control gets
much smoother and easier to handle.  So your score goes up.  I recally maybe
one feature, I think it was the countdown timer before, but not during,
each race, that's too fast on the '020, but otherwise, this is apparently a
very well done game.  Which proves than anyone writing games which work 
worse on a 68020 than a 68000 based system is out to lunch.
