I can manually switch it with "iwconfig wlan2 rate 36M", for example, but with an auto, "iwconfig wlan2 rate 36M auto", it drops back to 1Mb very soon.

Larry's reply was "the rate-control mechanism works the way it did before" - I am  not sure about the "it did" bit - same as v1 (rate stuck at 1Mb) or same as the prototype patch for 2.6.27 (rate changing with demand)?  

On my system is started at 1 Mbs and rapidly moved to 54Mbs. It went so quickly
that by the time I started a ping, switched terminals, and issued an ivconfig,
it was already at 54 Mbs.
