    Taint on write to /dev/mem, perhaps? I don't think DMIdecode needs to
    scribble on /dev/mem, does it? (Figure if a userspace program runs OK
    on a recent Fedora or RedHat kernel, it doesn't need to scribble on /dev/mem
    too much, because the vast majority of it is lopped out via a patch....)
