Bug#798317: xserver-xorg-video-radeon: Strange interaction of radeon config, screenshot and x11vnc

Finally I had the opportunity. If I reboot without RenderAccel and
EXAPixmaps, then, again, x11vnc and screenshot produce only a black
rectangle. If I then turn RenderAccel on and restart lightdm the
system starts without problem. If I then turn it off and restart
lightdm again everything is fine, including screenshot and
x11vnc. Could it be some required module that is only loaded when I turn on
RendeerAccel and then remains loaded after I turn it off?
Best regards,
