So check your system logs
(/var/log/messages, /var/log/NetworkManager, /var/log/daemon.log, etc)
and see what NM is sending to the supplicant.  You'll see something like
this:

Config: added 'SSID' value 'foobar'

That'll tell you whether the problem is NM or the supplicant/kernel.
You should see both the channel you gave NM, the SSID, the BSSID, and
"mode 2" being sent to the supplicant.  You may not know, but the
supplicant and kernel drivers have great leeway in doing what they want
with BSSID.  Also beware that some newer drivers simply don't support
AdHoc mode (bcma for newer Broadcom cards, newest Intel devices).
