After checking the back of the FreeBSD 2.0.5 and FreeBSD 2.1 CD's and
the handbook, I have not been able to find out any specifics on CPU
compatibility.  I noticed that the PC Hardware Compatibility link in
the Appendices of the handbook has disappeared (possibly due to a lack
of contributions, as it was pretty skeletal in the 2.1 release).

My basic question is this:  am I playing with fire trying to use Cyrix
CPU's?  My MainBoard seems to run FreeBSD 2.1 just fine with an Intel
80486DX(33), but when I rejumper and put in the Cx486DX2(66), I get
random reboots, shell and grep doing SEGV's, etc.  This happens with 
either or both caches enabled.  The system is so slow with both caches
disabled that I am better off running the DX than the DX2.

Since AMD quit making 5V CPUs, options for 5V main boards are a little
slim.

Suggestions?
