I have a Dell laptop set up with Fedora 11 (32-bit version), and I've been running kicad-20090216-final successfully and happily. The laptop has an ATI mobility Radeon HD3670 video card, and I've had no trouble using the open source radeon driver.
Recently (finally) ATI released the Catalyst 9.8 driver, which finally brings support to the Fedora 11 linux kernel, and I installed it. With the ATI driver I've noticed that screen refreshes in pcbnew are extremely slow - you can almost see the individual traces popping onto the screen, one after another. With the open source drivers, the refresh is almost instantaneous. Anybody have any thoughts as to what might be going on here? (I posted a similar message a few months ago, but at that time I was running the 64-bit version of Fedora 10, and I though the issue might be related to buggy 64-bit video drivers). Thanks for any pointers! Ryan
