Comment 2 for bug 520608

Follow up: problem in 5100 ABGN driver. Kind of sucks that I takes down plasma though.

I can't find it again, of course, but I did find a post that suggested installing the edge drivers would fix the problem.

sudo apt-get install linux-backports-modules-karmic

...and viola! All is well once more and the penquin is happy. (Don't taunt the penquin!)
