I don't think memtest86 supports PAE, so AFAICT it can't test more than
4GB of memory.  What's of more concern to me, though, is that running a
simple memory-testing application on 7GB of RAM under NetBSD/amd64
produces a near-immediate hard system hang early in the first test -- which
does not occur with a test size of, say, 4GB.  Obviously, *NetBSD* should
not hang like that.
