Just in case it's helpful to know..
I've seen something very similar to this (variously "FPU unavailable"
and a dump like the above, or "FP exception" with no dump) from CWSDPMI
on a system with a known-buggy CPU (Intel P24T "Overdrive" which is an
83MHz 486DX. This CPU also caused OS/2 to commit seppuku with an
"internal processing error at location [long address]".)

What hardware do you need for testing, and what needs to be run to get a
good test? I have these boards here that I could set up with some
reasonable amt of memory (up to 16mb) if you've got something smallish 
that would work to test against 'em:
386SX16 w/ 387SX16
386SX40, no mathco
386DX40 w/ 33MHz mathco
386DX40, no mathco
486SX25, no mathco.

Yes, I do have a weird collexion of old hardware :)
