I'm experiencing the same issue here, using radeon's drivers on an ATI
Radeon 9200 Pro. 

In my opinion it's related to the OpenGL version we're running; probably
the Gnome Shell (specifically Mutter) requires some OpenGL extension
that were introduced with OpenGL 1.4 that we don't have, since we're
stuck with OpenGL 1.3.

You may find which OpenGL version you're running with
    $ glxinfo | grep -i opengl

      OpenGL version string: 1.3 Mesa 7.10.1




Regards.

According to the laws of aerodynamics, the bumblebee can't fly either,
but the bumblebee doesn't know anything about the laws of aerodynamics,
so it goes ahead and flies anyway.
