This happens when switching to runlevel 5 as well as when running startx.

Maybe Egbert's patch introduced a bug?

I'll try to reproduce this issue on my 915G machine tomorrow. If you could disable the patch in xorg-x11-driver-video and rebuild the package for testing
this would be really appreciated.

Yep, removing that patch gets me something that works again.

Thanks. I've removed the patch. Fixed for STABLE.

- removed xf86-video-intel-memleak.diff, which resulted in a
  Xserver crash (bnc #439642)
