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.
