I'm a owner of Radeon HD 6850 and use only linux (expect for games and some video authoring and conversions). The FGLRX driver did not work for me, when I login, the gnome-panel appears filled with artifacts, blinking, and with the logo "unsupported".
I think I can give my feedback about the work on xf86-video-ati and kernel kms posting here how I'm doing this.
-First step I've done was download the snapshot from drm-radeon-testing kernel, patched with KMS support for Barts chip:
http://git.kernel.org/?p=linux/kerne...68c134448e03a5
-Extracted the kernel.
-then, just to be sure all files are patched to the 2.6.37 final, I download and applied this: http://www.kernel.org/pub/linux/kern...-rc8-final.bz2
-Downloaded and ALL copied these files to /lib/firmware/2.6.37/radeon/
-Compiled and installed the kernel. (using my old config)
-Downloaded the source from Debian experimental for xserver-xorg-video-ati and libgl1-mesa-glx.
-Downloaded Mesa-7.10 (ftp://ftp.freedesktop.org/pub/mesa/7.10/)
-Downloaded xf86-video-ati from git: http://cgit.freedesktop.org/xorg/dri...9cbd03ff0f4b82
-Copied the debian directory from Debian sources to inside the sources of respective packages( mesa and xserver-xorg-video-ati ) and run dpkg-buildpackage for both.
-Now I have a 2.6.37 with kernel mode setting supporting radeon barts chips and open source driver fully working. At this moment I'm using gnome-shell, tested glxgears, all working fine. If I test something else I post here.
