Comment 54 for bug 511001

Okey, so I found what I was looking for, a way to revert the disabling of all the 3d stuff (here: https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes)

These are the commands that do the trick:
echo options i915 modeset=1 | sudo tee /etc/modprobe.d/i915-kms.conf
sudo update-initramfs -u

The stability issues don't seem to apply for my graphics chip:
