Well... I had it running with an ATI card...

There it says something about how you do!
And the ATI drivers can be tricky, I haven't tried the latest ATI drivers, so I cant tell if they work. But the 8.10.19 (or what ever it was) did not work. The earlier version 8.8.xx did work.
The only issue was that the sky got weird.
Good help on installing the ATI drivers can be found here and on fedoraforum.org, otherwise: google
If U find it too tricky: go get the rpm from livna: http://rpm.livna.org/
Dont mess with the two different repositories! (read this: http://dag.wieers.com/home-made/apt/FAQ.php#D
I prefers "dag", and the packages that I cant get from dag, I download from livna // fedora.us
Now a days I often compile those stuff myself.
