X server crash in dual head mode with one monitor turned off !!

[paul verstraete <paul verstraete mech kuleuven ac be>]

I use a radeon9700 pro and a dual head set up.

The Xorg.conf file claimed i had two identical monitors after using 
system, which was not the case (after correctly entering the two 
different monitor type into the system-config-display tool). This led to 
a Xserver crash at startup.

With one monitor turned off, the X server crashed also (could not detect 
the second monitor). It would be a nice feature if the probing of the 
second one could be skipped in that case ...
