No, you are right they don't trigger MCA. Hmm I didn't have any of those back then, my lockups came from the bus mostly... Really if you have such lockups they may also happen on x86, did you try the card there? At this point your best bet is probably replay the crashing sequence until you can reduce it to the offending couple of commands.
