I am now in the middle of bisecting (currently at d888a4c) and interestingly the original problem does not occur at that commit, but the modes of my external monitor get misdiagnosed (no 1680x1050 resolution anymore) - the internal one works fine. That happended somewhere between 0a4de47 and d888a4c. I will skip this issue for now and keep bisecting the old issue.
