it's been disabled by 116_8xx_disable_dri.patch in the official xserver- xorg-video-intel ubuntu packages. You can try using drivers from this PPA which has git snapshots from upstream without that patch. This is for jaunty or karmic, intrepid ones are not maintained in there any longer. Don't forget to upgrade drm at the same time if you are grabbing individual packages, it would be better to add it to your sources and upgrade the whole stack at the same time.
