Phoronix: RV770 Support Added To RadeonHD Driver

The Novell developers behind the xf86-video-radeonhd driver have yet to receive their hardware samples from AMD for the Radeon HD 4850 or Radeon HD 4870, but there is already AtomBIOS-based support for these next-generation graphics processors. This open-source driver now has basic mode-setting support, but the 2D and 3D work is still to come.
