While testing a ATI Cedar equiped laptop I could not get the EDID for 
the interal LVDS in user space. I tried xrandr and xcmddc with no results. 
But the /var/log/Xorg.0.log showed that EDID was detected and hwinfo gives 
the monitor manufacturer. Still user space applications needs the complete 
data block to configure the monitor.

The driver is Radeon-1.3.0 build from git master 80ba041a .
Here some more details:

kind regards
