This fix sounds related to the R300CheckComposite function in the xf86 -video-ati (xserver-xorg-video-ati) driver. The ATI RS482 [Radeon Xpress 200M] is based on the Radeon X300 (RV370) chip. It has also recently been found that some RS6xx seem to have R3xx limitations as far as clipping is concerned. See https://bugs.freedesktop.org/show_bug.cgi?id=58469 for more info.

So, here's the chain of failures that I see... at initial login screen, there's a complaint about not being able to use the second monitor because the 3d virtual desktop cannot exceed 2048x2048 login menu doesn't seem to register my choice for unity 2d. logged in, i can't un-clone the built-in display and the external 15" panel because, again, the gnome settings apparatus is complaining about illegal display offsets. .... and * I DON'T EVEN WANT 3D !!!! .... the defaults should force everything to 2d if the hardware doesn't support accelleration at the resolution you have. .... performance is more important than prettiness... unity 2d should be the default if there's only software 3d.
