Axel Dörfler 5472c0c23e * The VESA driver now tries to find the PCI card that it is controlling by
checking the physical frame buffer location.
* This allows us to map the whole frame buffer at once, which means there is no
  need anymore to remap the memory on mode change.
* Also, this will ease the burden of the MTRRs, as the memory size will be
  properly aligned.
