Actually I had a similar problem on monday using an update to date driver from git.  Something to do with turning on the second output blanked both screens.  This was using just fvwm and setting 
things directly with the command line xrandr tool.  That being said, I have not had a chance to try to repeat the situation and can not narrow down the details.  I was just starting a presentation, so 
a few xrandr twiddles was all I had time for.
