    xorg-edgers ppa and recent kernel should suffice. Sorry for being not-elaborate - in case you're in trouble just write here.

      GL vsync is currently busted on radeon in mesa git master due to the intel dri2 swapbuffer changes:

        So should it work with r700 (4850) and newest versions of xorg-server, libdrm, xf86-video-ati, mesa compiled from git repositories?

        I've xorg server version as below:
        Code:
        X.Org X Server 1.7.99.3                                                 
        Release Date: (unreleased)                                              
        [    20.816] X Protocol Version 11, Revision 0                          
        [    20.816] Build Operating System: Linux 2.6.33-rc6 x86_64            
        [    20.816] Current Operating System: Linux localhost 2.6.33-rc6 #1 SMP Sun Feb 7 14:20:20 CET 2010 x86_64
        Also I've KMS enabled with IRQ support and still vsync does not working.

          As I just said, and you quoted in your reply, GL vsync is currently broken in mesa git master. You need to reset your tree prior to that commit or use mesa 7.7.

            I've overlook the detail about the master mesa branch - sorry for that and thanks a lot
            I've recompiled mesa using sources from 7.7 branch, and now XBMC is working great with vsync on. Only Kwin from KDE 4.4 won't get vsynced, but I can live with it.

              Use Mesa 7.7 and compile xf86-video-ati from git.
              And now it should work since EXA vline support was committed a few days ago :
