Comment 7 for bug 350789

As this is the first google hit on the subject;

Just to let general users know, the fix is included in the following packages:
     linux-image-2.6.28-15-generic 2.6.28-15.52
     linux-headers-2.6.28-15-generic 2.6.28-15.52

I had to manually download them as the prescribed method of enabling the proposed packages still didn't make the updates available on my system.

They are available from the following locations if you have trouble locating them:
