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.
