  The m68060 trapped instructions shouldn't make your system run as slowly
as I seem to remember you mentioning before, unless something is running
that is using an extremely high usage of those instructions.  If that were
the case, then vmstat -i should show an extremely high rate of
'interrupts' for the m68060 traps.

  This seems rather odd, and I'm not quite sure what might cause it.  I
am currently running a gcc4 compiled -current system on an m68040 system
and have not seen that.  I've got a 4.0 kernel (built with gcc3 at the
moment) and a -current kernel (built with gcc4) ready to test on my A4000
which has an m68060.  I guess I will also need to rebuild the 4.0 release
using gcc4 to try as well, if the -current kernel works.
