It is a (small) regression to 3.7.10 with intel integrated graphics i915
- but nevertheless :
With an external VGA display (1680x1050) and a closed internal LVDS1
display (1440x900) the external display starts X11 with 1440x900 - for
kernel 3.7.x.
With 3.8.2 (and .1) now the external display is driven with just 800x600.

Hm, sounds like we fail to properly read the EDID. Can you please boot
both the working and broken kernel with drm.debug=0xe and attach the
complete dmesg?
To keep everything together please file a bug on bugs.freedesktop.org
against DRI -> DRM(Intel) and attach the files there together with
your quick description of the regression above.
Thanks, Daniel
