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...
Intel G45 chip
Linux 3.12.5
xf86-video-intel (git but most of the 2.99.xxx versions I tried failed too)
X server 1.15.0
libdrm 2.4.51
I will attempt to bisect if I have time
