The 80i FPU is disabled in hardware.  I once saw the restoration
procedure and gagged.

palinux has nearly all, but not 100% of the FPU emulation code.  I
don't recall why I omitted a couple of things -- probably due to
structural issues fitting them into our kernel.  We had also made
a decision not to support FPU-less boxes.

If Grant can't find one, I'm pretty sure we have a 712/80 CPU board
around somewhere.
