Most if not all 802.11g cards will detect .11n networks even in greenfield mode. further analysis needs a .11n card in that case, but it's a start

Once the ath9k drivers settle we'll have decent support for .11n cards in linux it will be easier. It'll also be easier when the draft is finalized and the moving target stops.
