--- Comment #2 from Ralph Plawetzki <ralph at plawetzki.net> ---
I did some more investigation and upgraded to the latest packages again
(intel-dri-10.2.2-1  linux-3.15.2-1  mesa-10.2.2-1  mesa-libgl-10.2.2-1
xf86-video-intel-2.99.912-1) which reproduces the issue and makes the display
stay dark.

Then I only downgraded the kernel (3.15.2-1 => 3.14.5-1) and voilà: the system
boots fine.

So the actual problem seems to be in the kernel, not in one of these:
intel-dri-10.2.2-1 mesa-10.2.2-1  mesa-libgl-10.2.2-1
xf86-video-intel-2.99.912-1
