SON OF A GUN! My problem is apparently fixed!
Here's what i did:
1) took out my cpu, and removed all lables from it. This included the little paper inventory tracking tag, and the plastic warranty lable (it was already out of 30 day warrenty). DO NOT REMOVE THE WARRENTY LABLE IF IT IS STILL IN WARRENTY!
2) Removed the cheezy rubberish heat transfer pad from the CPU fan.
3) I had some really good heat transfer grease, the nice gray, thick, gunky kind, and slathered (well put about enough for the size and thickness of a dime or small coin) it on th processor.
4) Put everything back together. I will note that I put the cpu fan on before I pushed the ZIF socket lever back down. This was an accident, and probably didn't do anything.
5) Reset my motherboard to 100Mhz memory, and full (350Mhz) speed.
My usual test has been multiple, concurrent long compiles, like the kernel and Window Maker. I would get consistant segfaults and/or ASM errors EVERY time.
Now everything works normally. My guess is that the labels created small hot spots in critical areas of the CPU. The rest of the CPU would stay very cool, but just a few hot spots would exist. Probably the combination of the transfer grease and removing the labels eliminated the hot spots and everyting works very well. The interesting thing is that it would only happen under intense load, and ONLY under Linux. Guess you can be TOO efficient sometimes :)
My faith in AMD, FIC, and Linux is restored. My faith in myself is a bit humbled, however :)
