Hardware
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.

Not Yet Supported or Unoffically Supported
Cards in this group are unsupported as of Catalyst 10-12. The Catalyst driver may run on these cards, but it is not guaranteed (and you will be stuck with an "Unsupported Hardware" watermark unless you hack the control file). Full open source support is forthcoming in Linux kernel 2.6.38.
* CAICOS Radeon HD 6350 * TURKS Radeon HD 6670 * BARTS Radeon HD 6850/6870 * CAYMAN Radeon HD 6950/6970
Old Radeon Legacy (Open Source)
These cards are no longer actively supported by AMD as of the 8.28.8 fglrx driver. Unless you run an ancient distro, using the open source drivers is your only option.

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.
