1. Update your /etc/apt/sources.list to include the backports
deb http://backports.debian.org/debian-backports squeeze-backports main non-free contrib
sudo apt-get update
sudo apt-get -t squeeze-backports install linux-image-3.2.0-0.bpo.1-686-pae linux-headers-3.2.0-0.bpo.1-686-pae
...or linux-image-3.2.0-0.bpo.1-amd64 if you have that :)
4. say yes if you're sure you want to add the additional packages.
5. don't walk away...you need to press the OK button for something and quit a section on non-free stuff.
6. reboot and hopefully you'll have a new list in grub and then boot'er up! wheeeeeeeeze!
