I made sure to check Intel's support page and download the firmware just in case the kernel didn't contain it (it did) and then I went on to apply all the usual advice for troubleshooting wifi cards that won't load. Everything looks fine, except that the card doesn't load. Ethernet works fine, wifi works fine if I use a TPlink USB key.

Likewise, here's the module list. I'm at my wits' end here. Pointers would be appreciated.
