    Not necessarily. I have a test box that just crashes if the graphics card is
    not posted.

    You may try to use 's2ram --force --vbe_post --vbe_mode', if you haven't tried
    that already.

    Still, if the card is a 7300 or higher, that need not work (at present we don't
    know what magic is required to make these cards work).
