Little late with news, but still ….. The ATI/AMD fglrx driver for x86 and x86_64 Linux is now available! . In addition to the AIGLX support, the fglrx 8.42.3 driver includes X.Org server 1.4 support, video playback improvements, more performance improvements, and Rialto AGP fixes. While this driver quite promptly supports X.Org 7.3 / X server 1.4, it does not contain Linux 2.6.23 kernel support. The new features mentioned in the release notes include support for AIGLX, X.Org 7.3,

products older than the R600 now being enabled, and a new 3D user interface in the ATI Catalyst Control Center Linux Edition.

AMD Proprietary Linux Release Notes for 8.42.3. For the time being the 8.42.3 download link is here. (x86_64)

P.S. Expect updates to my How-Tos for ATI driver installation and running Compiz Fusion on openSUSE with AIGLX, instead of Xgl … give me few days.
