Although game writers seem to be guilty more often than non-game writers, let's
add a non-game product to your list of titles that won't run.  SoundScape (from
Mimetics) will NOT run on a 2620 without the cache disabled.

Didn't somebody promise to post a list here a long time ago of titles that
wouldn't run on 68020 boards?  Perhaps it's time somebody accumulated a list
for all to look at before getting bit.  Possible work-arounds (such as
nofastmem, nocache, etc) might be useful for people that add a 2620 (or
similar) and find out that suddenly an important piece of software stops
working.  Then somebody can take this list, publish it in a magzine and with
a lot of luck, some publishers might even fix their code.  We'll all benefit in
the end.
