OK. I tried this:

*) Set the essid/key/mode to the appropriate values but I still see the
   freq being 2.457GHz (channel 10) while the AP is using 2.412GHz 
   (channel 1). Hence no communication between the card and the AP.

*) Changed the mode to ad-hoc and then tried to change the channel
   (or the freq for that matter) to no avail.

The bottom line is that (regardless of the AP) I seem no to be able
to change the channel on the card. In Managed mode it gives me
"operation not supported" (which from your statement above it is
a legitimate behavior) and in ad-hoc mode it seems to run with
no error but nothing changes.
