Also, the OpenGL PixelCopy functions are ridiculously slow.
You mean glReadPixels? Yes, it''s slow, but it''s not necesseraly OpenGL''s fault. The AGP bus is optimized for writing to the Video memory, not retrieving data from it so reading back pixels, which requires the driver to lock the framebuffer in video memory and send data back on the bus to system memory is slow. If you want software rendering, i think MesaGL is what you are looking for.
