That's what I thought as well, but it's certainly not true on my system. I
spent three days trying to get the live CD to not crash. Every time, the
entire system locked up with maybe 30 seconds (usuall less) of getting to
the desktop. I tried installing from the Alt CD and that worked, but it
locked up as soon as I launched my newly installed system. Once I switched
to the Athlon 64 system, things went fine.

Anyway, it turns out that the problem apparently was memory related. I've
been running now for 24 hours on just the single stick of ram, and
everything seems to be running fine. I had tentatively dismissed memory
since it was still failing to boot the live cd even after passing the
memtest, but it turns out that somehw in the last few days my live CD had a
tiny nick taken out of it, apparently right where some crucial file lives,
so that was causing it to fail. I had just installed less then a week ago
from the exact CD, so it didn't occur to me that it could now be bad, but as
soon as I burned a new copy of the CD, everything worked fine. I'll give it
a few more days before I finally consider the matter completely resolved,
but for now I'm cautiosly optimistic.

Thanks for everyoine's help!
