I have an ASUS SP3G w/ AMD DX4/100, and I recently was experiencing very
similar symptoms under FreeBSD 2.0.5 and NetBSD 1.1_ALPHA.  I believe
I have fixed the problem on my box, it was the CMOS "CPU to DRAM write
buffer" option.  After disabling it, my machine hasn't crashed, even
though I've been torturing it with eatmem/bonnie/make. (load of 5.xx)
My SP3G has the Intel Saturn II chipset.  You might want to check for 
a similar option on your mainboard, it is worth a shot.

I'm still not happy that my AMD was not truly a "drop in" replacement
for an Intel, but I'm not 100% sure whether it is a CPU or mainboard
problem.
