I can't comment on the technical details, because I am not an OpenGL expert at 
all. But I'd like to test it when you're finished.
There may be a workaround for the glReadPixels slowlyness. I've seen that both 
mplayer and xine can draw a 2D movie fast onto an OpenGL texture, as long as 
the player window isn't overlapped too much. At least they pretend to use 
OpenGL to render the video. Once the window is overlapped, it becomes slow as 
hell( 1 fps, if not less).

Sure it's an ATI driver bug. But I can't change my notebooks graphics chip ;)
To be fair: The ATI driver is constantly improving, and it's really useable 
now. The only thing that bothers me right now, is the recent regression on 
old cards introduced with fglrx 8.19.10. I really hope they fix it.

How is the nvidia driver doing recently? Does it have acpi suspend support? 
How is the speed compared to the Windows drivers?
