    ah ok, so at this stage swsuspending a X desktop doesn't work in general
    case, of course depending on video hardware? If X had some notion of
    suspend/resume things would be easier, than insisting every single
    driver save and restore all. After all the pci config space should be
    enough for kernel drivers?
