In my understanding, it is a 2-part driver: the first part is in the kernel (i915.ko) and the second part is a Xorg module named xf86-video-intel (or xserver-xorg-video-intel in the Ubuntu package list).
The links above mentions the Xorg module.
Please could you try to find the package version on your system to confirm it is a 2.9.0 version problem?
For example, you can try the following command line:
dpkg -l | grep xserver-xorg-video-intel
