Public bug reported:

After an upgrade to the linux-image-3.2.0-56-generic kernel on Ubuntu
12.04.3 LTS, my laptop had no wifi. No lights, nothing in network
manager to even acknowledge the existance of a wireless capability.

On rebooting into the previous kernel linux-image-3.2.0-55-generic it
works again (and thus I am able to report this!).
