Intel GPUs as well. I think that at this stage, there's only sufficient documentation available to do a GPU back end for Intel and ATI, not nVidia (though I don't know if any progress has been made via reverse engineering, perhaps by the nouveau project). I think anyone who pursues this angle would be well-advised to look at more than one architecture.
