    First make sure you can build and install the sources as shown here

    Next make sure you have acceleration working.

    Next, download the patch from this location and save it as the filename 'patch' in your xf86-video-radeonhd directory.

    now you have 2 options.

    From the xf86-video-radeonhd directory type the command
    dos2unix -n patch fixed.patch


    From the xf86-video-radeonhd directory type the command
    sed 's/.$//' patch > fixed.patch

    finally from the xf86-video-radeonhd issue the command
    patch -p1 < fixed.patch

    I hope this helps

    Note you can remove the patch with this command if it causes trouble
    patch -p1 -R < fixed.patch
    Thank You. The problem is that I've installed radeon{,hd} and drm in some another way, through ppa's and, lately, with easy-drm-modules-installer, so I do not have xf86-video-radeonhd directory ... I will investigate the situation more, I'm up-to date to tormod, pendretti, xorg-crack and radeon-rewrite (with both radeon{,hd}) ...
    Thank You,again ...

      gtkperf doesn't seem very consistent, I ran the test a few times at x1000 with your latest patch. These are the results
      1 Total time: 103.18
      2 Total time: 104.41
      3 Total time: 105.26
      4 Total time: 99.90

      On the fourth run I moved the mouse cursor between the screens (dualhead)

      Same with x100 if I move the mouse cursor to the other monitor there's a 1 second diffrence between the results.

        You should set your cpu to performance mode, otherwise you bench speedstep/powernow...

          I got coolnquite disabled in the BIOS.

          cat /proc/cpuinfo says 2800.242 MHz

            As I have stated before I'm not a fan of gtkperf.

            I get my most consistent results when running gkrellm along side it for some strange reason.

            also to see what freq your cpu is working at at the moment you need to

            cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

              that's great news !

              thanks bridgman & kudos to Yang Zhao / Yangman


              thanks for making the (already fast) radeonhd even faster !

                I think Matthias just posted a patch to the radeonhd list which turns on clock gating for 5xx/rs6xx parts, which should give some additional power savings. I stress *should* because nobody has had a chance to actually verify power reduction yet
