Hi everyone.

I just bought a Cyrix 387-SX math coprocessor and installed it a few
hours ago.  When I brought up 386BSD it recognizes the chip fine, and
some programs (whetstone benchmark, sc) seem to run fine with it.
 
However, ps -aux barfs with "floating exception" immediately after
printing the first report line.  ps -aux worked fine (but slow) without
the coprocessor.

Another program I've been trying to get working (almost useless to try
it without a math chip) is ephem and it also barfs with a floating
point exception.
 
Why does this happen?  Do I need to recompile anything?
