That's not quite true, my atifs replacement supports everything on the 
fragment side, and that card doesn't support GLSL(not even ARBfp). Also on 
the vertex side there are cards that have ARB only and not GLSL. I don't yet 
know if we can replace the fixed function vertex pipeline on r200 cards, as 
the 128 shader constants seem rather limiting, especially when it comes to 
indexed vertex blending. However, it should be able to do non-indexed vertex 
blending just fine, and we can get rid of the color conversion.
