After upgrading to a new fancy randr 1.2 radeon driver, I get the wrong resolution in rhgb and gdm. When I log in I get the right one (gnome restores my previous settings).

The right one (panel native) is 1680x1050, and the one chosen is 1360x768. To make things worse, the panel doesn't like the mode settings chosen for 1360 as the rightmost 50 columns are basically noise.
