I have marked bug 398026 as a duplicate of this bug, even though it is
reported for GM45 and this one is for 965GM. We usually don't duplicate
bugs reported for different chipsets, but I think it is very likely that
this is the same newly introduced bug.

The previous version of xserver-xorg-video-intel (...git20090602) had a
bug in which only the preferred mode from the EDID information would be
available (https://bugs.freedesktop.org/show_bug.cgi?id=20801). In
...git20090702 this bug is fixed and also other modes are available. The
problem seems to be that for LVDS output the driver sometimes chooses a
mode with the preferred resolution, but with a higher frequency (85 Hz
instead of 60 Hz in bug 396171 and 60 Hz instead of 50 Hz in bug
398026).

As far as I can see, this bug is not upstream yet (it was introduced
only recently) , so we should get it there. Upstream prefers to focus on
a single use case, and I think Chris' (bug 398026) describes this
better, as he has xrandr output and Xorg.0.log for both 20090602 and
20090702, so it's easy to see the difference. I don't have time to take
this upsteam right now, but maybe Chris and Oded can take a look at each
other's report and report any striking differences that I haven't seen.
Also, if you could take a look at
http://intellinuxgraphics.org/how_to_report_bug.html and see if there is
some additional information that you may give so that we can include it
upstream, that would be nice. To keep the two use cases apart, I think
it is best if Chris attaches any additional info to his report and Oded
to his.
