There is a big problem. When you programm a GPU, you can't use the same 
code for an ATI, an nVidia or an Intel one.
WHO have 10 graphic cards in his computer?

Also, to my knowlege, GPU still don't do double precision FP operations, 
only single precision. POV-Ray require double precision for most of it's 
computations, hardware supported triple or quadruple presision would be 
nice.

GPUs are made to work only on triangles, POV-Ray use several, 
non-teselated, primitives. You'd only be able to render triangles, 
meshes and bicubic parches on the GPU.
