Only 256MB of the Videoram will be accessible by the processor directly, the
rest is only accessible by the GPU itself. 2D acceleration relies on software
fallbacks, so the framebuffer and pixmaps have to be CPU addressable. As e.g.
textures are typically uploaded by DMA, the whole memory can be used there.
That said, we don't have 3D yet :-]
