[ don't forget there is a freebsd-smp list ]

According to Alfred Perlstein:

See <URL:http://www.freebsd.org/~fsmp/SMP/SMP.html> for details.

It won't work on Cyrix/AMD processors because they don't use the same APIC
as Intel. There is a document about OpenPIC for these processors but only
the AMD 640 chipset implement it (to my knowledge).
 
For now, SMP == Intel.

You should be able to run your P150 at 2.5x 66 MHz (== 166 MHz) without
problem.
