    Well, at least r128's and radeon's need the memory controller and PLLs
    initialized by the BIOS/firmware, we don't have documentation about how
    to acheive that ourselves (and this can depend on the specific wiring of
    a given card anyway).

    This is not possible with most modern cards without specific POST code
    provided by the chip manufacturer.
