    ps doesn't use kmem, and besides, in 2.6 we export that directly in
    proc. poking in /dev/mem or /dev/kmem is NOT something you "just do".
    THere are lots of pitfalls, things like PCI space, memory sizes/holes,
    cachability aliases etc etc that can ruin your breakfast if you
    use /dev/[k]mem...
