    Its used on the chip for the onboard audio. See drivers/sound/nm256*. If you
    have other sound chips then it is probably not needed.

    yywrap is a hack rather than generally safe feature and its not guaranteed that
    your videoram wraps neatly. Really the driver should have spotted the hole I
    guess.
