The old radeon driver did not support xrandr 1.2, the new one does.  xvidtune
is not xrandr 1.2 aware.  randr 1.2 handles multiple crtcs and outputs; randr
1.0 assumed one output per screen.  the xrandr 1.0 compatibility paths are not
well tested and in some cases the 1.0 compatibility output/crtc may not match
what's currently in use by the driver.
