The 'correct' way to downgrade a single package and its dependencies is "aptitude install packagename=version", eg. "aptitude install xserver-xorg-video-intel=2:2.4.1-1ubuntu10". Doing what Pablo Marchant suggested will probably end up uninstalling a lot of other stuff that you do not want to remove.
I am curious which backports repository is being used, exactly, and what driver version is being installed, since I have always enabled the intrepid-backports repository and the latest offered driver version is still 2.4.1-1ubuntu10, which has horrendous performance, at least on Q45.
