I think the "correct" fix is to separate managed and adhoc networks in
the network list...  Right now NM concatenates all networks with the
same SSID together, regardless of the network's properties.

Another thing to think about would be setting the AP's BSSID on the card
as well as the SSID, but that has a few problems, namely that (1) not
all drivers support setting the BSSID, and (2) roaming is then broken.
