However I found something out:
When I modprobe i915 I get a picture in picture so it seems both graphics a rendered at the same time and the i915 IGD has a too small modeset. With this I can confirm that the patch with my changes at #17 does at least set the correct modeset as then the rendered output is perfectly the same and you don't get that wired picutre in picture.
However whats stranges is that my PCI id is different. Could it be that there is a backlight quirk (or something like that) for the 0x0116 PCI ID that doesn't get activated for me as the PCI for me is 0x0126?
Also in the original Bug #1171940 the patch seems to fix the blackscreen and for me it doesn't but I can confirm that the quirk gets activated proberly. Maybe there is a related quirk that doesn't jump in action.
Ok the 3.9.0 [1] doesn't work also:
