ThinkPad T420 + kernel 3.8.x + external VGA display == wrong resolution

[Toralf Förster]

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.
