Yes, X -configure does DDC, but doesn't put the modes into the config 
file. I did look at ways of doing it, including using gtf to generate the 
standard timings, but I didn't get as far as a way of integrating this 
info into the list of available modes.
To do so now would be a significant change, and I wouldn't be happy if 
anyone tried to do it for v4.3. There is just too much chance that it 
would have a bad interaction with something which wasn't found until
after we shipped.

If you want to do anything with monitor detection, read up on the source 
code to see how modelines are handled in the server, and how we can add
more when we do DDC detection. We are really trying to do this at run 
time, not config time, since the monitor may have been changed
since the machine was configured.

One related thing; some flat screens and digital cards use non-default
GTF paramaters - a secondary timing curve (since flat screens don't need 
as much time for sync flyback) xc/programs/Xserver/hw/xfree86/etc/gtf.c 
doesn't yet support this.
(In addition it only generates GTF modelines specified by vertical 
refresh; occasionally a GTF modeline specified by horizontal sync or
pixelclock).
