Must hear from the AP?  Like, beacons?  If beacons aren't enough, how is
something ever supposed to associate?

The AP is detected normally via scanning (wpa_supplicant 'scan' and
iwlist scan) so the card is seeing beacons fine.

I'll reboot into the git kernel later today and redo the test on another
channel.

In this test, 'iw'.  I got about 3 seconds of packets from different
channels while trying to associate on 56 (I assume because the card was
doing a scan) and then the system locked.
