Comment 4 for bug 569122

I've now tried linux-headers-2.6.34-996-generic_2.6.34-996.201004231022 from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/current/

This resulted in hibernation failure: the screen went black, I could here some regular hdd activity, but after ~10 minutes I did a hard reset (which caused fsck on reboot).
