The improved crtc handling in ati's latest code drop may help in this
situation.  Also when using a DVI port, I think crtc1actually drives
the DVI port and crtc2 drives the LCD.  you might want to try:
Option MonitorLayout "TMDS, LVDS" 
however, I'm not sure the crtc code in cvs can properly handle output
swaps at the moment.

I suspect the mergedfb support in cvs may be somewhat broken. 
Unfortunately, I haven't had a chance to test and fix it yet.  this
also may be related to the reversed crtc mappings I mentioned above.
