Xorg.0.log
With the latest git xf86-video-intel I am getting a segfault immediately upon
starting the X server. The last known working version of the driver was
1.15.0 which unfortunately not longer builds against the latest X server.
Here's the backtrace from GDB...
Program terminated with signal 11, Segmentation fault.

Obligatory version information...
