11/7    More Linux memory question: 1024 MB: I ran memtest86 (great program)
        and it sees all 1024 MB, so I think that means it's not a bios issue.
        (also I use a PCI video card, so no AGP) /proc/cmdline says:
        auto BOOT_IMAGE=Linux ro root=301 mem=1024M
        but meminfo (free, top etc) still say   MemTotal:  901392 kB
        Any suggestions as to what I should try next?
