Officially Supported (Catalyst & Open Source)

The following hardware is supported by current releases of the Catalyst/fglrx driver. Open source drivers will work as well. Note that RadeonHD 6xx0 chips will need kernel 2.6.38 for open-source mode-setting, xf86-video-ati/radeon 6.14.0 for 2D acceleration (EXA/Xv), and Mesa 7.11 for 3D acceleration.

Radeon (Catalyst Legacy & Open Source)

ATI/AMD dropped Catalyst support for these cards in Catalyst 9-4. These cards are supported with the legacy ATI 9-3 Catalyst release, but you MUST use a kernel 2.6.28 (or earlier) and Xserver 1.5 (or earlier). For example, you can use Catalyst 9-3 if you're running Ubuntu 8.04 or Debian Lenny/5.0. Open source support is good and 3D is still improving.
