First, note that there is a difference between memtest86 and
memtestplus.  I recommend the latter (and am listed as the maintainer
of it).  Second, I do not have any 64-bit machines to test on.  Given
that it's chipset-dependent, I'm quite loathe to assume anything about
its behavior.  It's easy enough to test, though -- just change the
ONLY_FOR_PLATFORM line in the Makefile, and let me know what happens.
