We are nearing the end of my expertise here. It seems the
xserver-xorg-video-intel package includes the i915 module, which your
computer is detecting and using.
So it looks like you'll need to remove that module, and add in earlier
module. But I'm not sure of the name for the earlier module. The
commands would be something like this (NOTE: don't do this until you
determine the name of the module)
rmmod i915
modprobe i845
/etc/init.d/gdm restart
(for that last command, use "kdm" if you are using the KDE login manager).
If that works you'll need to blacklist the i915 module, and enable the
earlier module on a more permanent basis - usually through an entry to
the config files. Gustin, or others are more knowledgeable here though
and can give you more specific details.
