connecting a Philips 32PFL5404H [1] to the ASUS EeePC 701 4G worked with version 2.8 and maybe even 2.9.0 of the Intel driver. With 2.9.1 it does not work anymore and I get a similar picture as in [2] (different monitor).

In #intel-gfx on irc.freenode.net ajax suggested, to test it with VESA. Unfortunately I could not test that yet, because I had forgotten to install `xserver-xorg-video-vesa`. But KMS seems to be the culprit indeed. Checking the Debian changelog around the time this issue started to appear [3], KMS was enabled by installing `/etc/modprobe.d/i915-kms.conf` enabling KMS.
