The succesfull workaround for Xorg crashing on Intel GM45 integrated
graphics on Lenovo T400 was to create the the following file
/usr/share/X11/xorg.conf.d/20-intel-gm45.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
Swtiching from SNA to UXA alleviated all the problems.
As a side note, gtkperf tool is very reliable to reproduce SNA Xorg
crashes.

Bug description:
For some reason easily triggered by Firefox 31 to 33.
Chromium and other graphical applications work without problems.
Firefox 28 from the live Ubuntu 14.04 usb drive, does not trigger Xorg
crash.
The crashes occur with the stock Xorg as well as Xorg-edgers.
One of the previous crashes was slightly different.
