RadeonHD 1.1.0 Driver
 

Yesterday the NVIDIA proprietary driver was updated as well as
the ATI proprietary driver and the open-source Radeon driver. Continuing
in this holiday excitement, the Novell developers have released the
RadeonHD 1.1.0 driver just moments ago. This open-source R500/600 driver
contains a few new features and fixes since the RadeonHD 1.0.0 release
last month.
