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.
