A colleague of mine (that I foolishly allowed root access to) made the mistake of using the driver/installer on the ATI site. After rebooting, X wouldn't load and the monitor went black *gasp*. I too followed the howto by Leigh
and I'll be damned if it didn't get X to come back to life. However, like those above, my system froze within the first minute each time I booted up (usually after opening Firefox but ultimately even moving the mouse around on an empty desktop would do the same). I'm fed up. I was forced to re-install F11 because the endless forum searching only to result in the same frozen box was just getting to be too much. What sort of default drivers is a fresh install using and why couldn't I have resorted back to those when all else failed?
