@Daniel

I think you were misled by the "ppa" in the link Joshua gave you. This is not like the standard ppa's on launchpad. Don't add it to your list.

Download the one or three debs that you need by hand and install them by hand.

The current mainline you get that way has wireless drivers about 3 month younger than backports 2.6.37.
