The output from my Vaio laptop to the external monitor (LG Flatron M228WD) is broken now. The screen is all messed-up once the boot messages from the kernel appear on it (see the picture at the link below).
I bisected it down to f8aed700c6ec46ddade6570004ce25332283b306 ("drm/i915: Set crtc/clone mask in different output devices"). I doubled checked that reverting this commit from 2.6.31-rc9 fixes the problem.
The picture of the bad output is here: http://www.aei.mpg.de/~crmafra/bad_output.jpg
as well as my config: http://www.aei.mpg.de/~crmafra/config-2.6.31-rc9.txt
and dmesg (with the above commit reverted): http://www.aei.mpg.de/~crmafra/dmesg-2.6.31-rc9+revert.txt
(the vga=0x0364 in the command line does not work since I enabled KMS, so I get a prompt in the beginning from which I choose vga=0. But the above regression is not affected by this choice because the command line was always the same during bisection)
If there is anything else I can do, just let me know.
