    A small number of laptop systems are known to pull this trick. There are
    other problems too - the video bios boot may make other assumptions
    about access to PCI space, configuration, interrupts, timers etc.

    Some systems (intel notably) appear to expect you to use the bios
    save/restore video state not re-POST.
