    Unfortunately, I haven't been able to find the link, so I could be wrong (if I am please shoot me!)
    Interesting, I just noticed one of the few fglrx bug reports that actually did get some feed back. And it looks like you are right. They intentionally crippled fglrx glReadPixels performance for consumer cards.
