If you've installed Debian "Squeeze" on your laptop or desktop with an ATI card, you may have noticed that your graphics performance wasn't all that it could be, or more artfully, it's in the toilet. You may have investigated this problem by googling and peeking in numerous forums, always feeling you're so tantalizingly close to solving the problem that you could forgo posing a question to the grep nazis at the Debian forums for one more day, just one more day, and you'll have the answer. You pull your hair out and bang your keyboard. Soda cans and junk food wrappers pile up on your desk. You start bizarrely rocking back and forth in your chair thinking it can get you closer to your holy land. Well, before you go that far and embarrass yourself and, well, me frankly, take a look at this page.
Hint: install linux-firmware-nonfree.
I would like to take this opportunity to thank everyone for promulgating the above link so that anyone out there wouldn't waste hours of their time editing xorg.conf files and reading logs and mesa-utils outputs while the rest of you are no doubt sunning yourselves, making love, and biting grapes off from the stems like they did in those old Roman movies.
