OpenSolaris Ships RadeonHD Driver
Phoronix: OpenSolaris Ships RadeonHD Driver
Since last September when AMD's new open-source strategy was unveiled, their xf86-video-radeonhd driver and NDA-free documentation efforts have largely been to improve its Linux customer base. However, with this open community enablement, it has also led to an improved ATI hardware status in Sun's Solaris Operating System. Introduced in Build 80 of OpenSolaris was the RadeonHD display driver and this R500/600 driver has now appeared in Solaris Express Developer Edition 1/08 and Project Indiana Preview 2.
FYI, the redeonhd driver is in the Fedora 8 update repository, so it looks like it will be integrated in distributions very quickly.
