I finally got some time to bisect this issue and found
drm/i915/sdvo: Set sync polarity based on actual mode
causes the bug.
And, indeed, reverting 81a14b46846fea0741902e8d8dfcc6c6c78154c8 on
126.96.36.199 or 2.6.38-rc8 makes my monitor detecting 1920x1200 again.
Please note, this patch is part of a 3-series together with:
drm/i915/hdmi: Set sync polarity based on actual mode
drm/i915/pch: Set transcoder sync polarity for DP based on actual mode

I heard, if you play a NT-CD backwards, you get satanic messages...
That's nothing. If you play it forwards, it installs NT.
