TravelMate 5720G and video card driver

Dear list members, I recently bought an ACER TravelMate 5720G, on which I installed Fedora 8. The laptop has a 1280x800 display resolution and an ATI Mobility Radeon X2600 video card (according to ACER web site --- but probably it is the same as ATI HD 2600 if I well understood) Fedora 8 does not have a specific driver for such video card, therefore it proposes a generic vesa driver, which does not handle 1280x800 resolution. Therefore I downloaded and installed the ATI driver for HD 2600, from ATI web site. Now the resolution is set correctly, but as a drawback the motion of objects (like windows) on desktop is very slow and jumpy --- awful effect, really!! Did anybody experience similar problems? Does anybody has a solution to suggest? Many thanks to you all!
