Although not on FreeBSD, I have seen similar odd crashes on a high end petium box which was shipped without a CPU fan. Putting one on solved the problem, again it was found that running the box with the lid off helped before the fan went on.

I've got a Pentium 133 here running 2.2-960612-SNAP, and it too was experiencing more or less random Segmentation Faults, Bus Errors, and/or Illegal Instructions. This behavior persisted despite swapping SIMMs several times. I finally resolved this with a strange fix: though the CPU can run at 133MHz, I clocked it down to 120MHz via jumper settings on the motherboard. I haven't had any problems with it since. I wonder if my problem is actually heat-related as well? Reducing the CPU clock may simply cause the chip to run cooler. Anyone else have similar troubles, or other ideas? -- delerium@ais.net
