If you don't want to/can't install a different card, maybe
try disable
i915 driver, kernel based mode-setting and use the vesa driver.
In this case you could try to boot with i915.i915_enable_rc6=0 and
using SNA:
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "SNA"
EndSection
If this doesn't work, try to disable acceleration in xorg.conf completely:
Section "Device"
Identifier "Card0"
Driver "intel"
Option "NoAccel" "True"
EndSection
