and this is the last attempt, when I booted a newer kernel:

cat /var/log/Xorg.0.log | grep Pageflipping
[    37.812] (II) RADEON(0): KMS Pageflipping: disabled
cat /var/log/Xorg.0.log | grep SwapBuffers
[    37.812] (II) RADEON(0): SwapBuffers wait for vsync: disabled

glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
301 frames in 5.0 seconds = 60.112 FPS
300 frames in 5.0 seconds = 59.986 FPS


vblank_mode=0 glxgears
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: default value of option vblank_mode overridden by environment.
16145 frames in 5.0 seconds = 3228.899 FPS
15667 frames in 5.0 seconds = 3133.278 FPS

then I set the vsync to off in kde desktop effects settings:

glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
301 frames in 5.0 seconds = 60.072 FPS
301 frames in 5.0 seconds = 60.015 FPS

vblank_mode=0 glxgears
ATTENTION: default value of option vblank_mode overridden by environment.

14340 frames in 5.0 seconds = 2867.876 FPS
14858 frames in 5.0 seconds = 2971.596 FPS

doing vblank_mode=0 kwin --replace has the same effect than setting off vsync
in kde desktop effects settings
