System: Acer Aspire 5022WLMi, Mobility Radeon X700 PCIe, X.org 7.2 Using xf86-video-ati 6.6.191 and radeonfb: When UseFBDev is enabled, the presence of an external CRT will cause the X server to crash on startup. Interestingly, MergedFB is disabled, yet appears in the log before the crash.

With the patch from bug 10442 the log output changes, but still the X server throws an error and quits.

Does it work with Option "MonitorLayout" "LVDS,NONE"?
It turns out that even fbset gives the error "FBIOPUT_VSCREENINFO: Invalid argument" So probably the problem is radeonfb. Sorry for the noise.
