screen flickers

Hello everyone!
I have a gateway laptop with a (ATI RS690M Radeon x1200 series Card) i was not able to get the ATI drivers to install at all the 1 click install failed after several days and the hard way would not work at all.
My question is is there a mesa driver that would take care of the flicker problem that you know of. i have tried all i could think of. maybe some other ideas might help. i have the latest mesa installed from the website…
