Subject: Weird problem with SetCPU FASTROM and A2620

I am having a weird problem with SetCPU 1.4 and an A2620 with 2 meg of 
32-bit RAM.  There is also an A2090 and an ASDG 8-MI with 4 MB of RAM 
in the system (a 2000, but you guessed that, didn't you...)

If I do the 'setcpu fastrom,' things will work OK for a while, 'rombash'
will tell me that it's a bit more than twice as fast, but after a while,
the system will weird out and start autorepeating characters that I type,
so if I type 'setcpu,' I might get 'sssssssssssssseeeetttttttttccccppppuuuuuu.'

Any ideas?

Incidentally, on compiles of a fairly big program of mine (about twenty
separately compiled source files), with *everything* coming out of RAD: 
(executables, source, libraries, includes), I see a performance improvement 
of 2.2X over running in 68000 mode.

Is that what one would expect and/or are there any other methods by which one
can improve the performance when using the '020?  Not that I'm complaining...

Oh yeah, the '20 makes playing anim files a lot more enjoyable because the 
number of timing misses and max deltas are much lower.
