The Sun FPA was a floating-point accelerator ... it is totally different
from the '881/'882 ... in order to use it, you have to access a device
driver.  You can't just use the m68k floating point insns.

I'm pretty sure I have some info on this board somewhere -- if you're
interested in writing a driver for it for NetBSD, let me know.
