Not sure if we want/need this, yet at least. This changes behaviour
which is not what refactoring patches should be doing, right ? if
needed it ought to be a separate patch, imho.

Furthermore on nouveau and AMD (iirc) front, some dual-gpu/optimus
systems use PCI_CLASS_DISPLAY_3D. So if we add DISPLAY_VGA perhaps we
should also check for DISPLAY_3D ?
