Note that if a program ever specifically asks for MEMF_FAST, and there
is no non-chip ram, that allocation will fail.  It is best not to specify
memory type if you don't need chip ram, so that you will get FAST if
available, but CHIP, if not.

The 1MB chip system is the first time in a long time that there is
not fast ram on board, first ever if the program "requires 1MB".

So, programmers: beware: MEMF_FAST is probably NEVER appropriate (since the
memory might not be particularly fast, anyway).

Rev 6 users: once you get some fast memory in there that doesn't break,
you should be OK, and we'd like to hear if there are software problems
on Rev 6 or other 1MB chip configurations if sufficient fast ram is
present.

I recommend populating the 2620 board.  It IS populated?  Well, that's
different: somebody must be cheating on the high address byte.

Leap all over the software vendor: have them contact C-A if they think
the problems are not their fault ... ;^)
