Just confirming, for me the bug manifests differently: I have a 1280x1024 external monitor, and X starts in that mode (with a little help in xorg.conf). However, g-s-d tries to be too clever and switches it to 1024x768, presumably because xrandr thinks that this is the highest common resolution with my internal monitor (1280x800). So I now get two unnecessary modeswitches during boot (my desktop session of course switches it back to 1280x1024).

So this is indeed a regression.
