Comment 36 for bug 379831

Ok, it's really easy ;)

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32-rc6/ has deb packages of fresh kernel snapshots.
All you need is downloading and installing headers and image files:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32-rc6/linux-image-2.6.32-020632rc6-generic_2.6.32-020632rc6_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32-rc6/linux-headers-2.6.32-020632rc6-generic_2.6.32-020632rc6_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32-rc6/linux-headers-2.6.32-020632rc6_2.6.32-020632rc6_all.deb

Then you should update your grub:

sudo update-grub

Reboot ;)

* Certainly you can compile it from sources but this way is the most simple :)
