Memory map and misc fixes. This completely reworks the way the driver

    detects available & accessible video memory and initializes the card
    internal memory map. Along the way, I re-ordered some of the stuffs in
    pre-init in order to remove some dodgy codepath, fixed various init,
    exit and vt switch issues, and overall made the driver more robust. The
    full memory map fix requires an updated DRM. The X driver no longer
    tries to position the AGP aperture, this becomes entirely DRM
    responsibility.
