What is slow with ATI cards? It seems that you should only need basic 3D acceleration to do what you propose. Is fglrx missing something that would be required for 2D rendering?
Texture upload is very slow. glReadPixels, glWritePixels and friends take ages. That means that blt, Lock, and Unlock is really slow. There is some hope at least: Xine and Mplayer can play videos over OpenGL really fast, maybe we can find out how they do it.
for glReadPixels, glWritePixels you can use the frame buffer object extension (or/with pbuffers) :)
Keep your Good work
