Maarten:

Could you attach /var/log/Xorg.0.log  to this bug?

I'm curious about details of what your X server has gotten from the EDID
fetch.  On my Dell Optiplex 745, the EDID fetch sometimes comes back all
zeros, instead of actually providing the monitor config data.

I have an xorg.conf that seems to more consistently fetch the EDID data, but I 
don't yet know why.
Two differences are that the line:
     Load "i2c" 
is deleted and a line is added:
     Option          "UseFBDev"              "true"

Things started working when I added these lines.  They seem to have
changed the timing of the EDID fetch such that it was successful more
often.
