Wait, really?  

Because I've used this iwpriv command successfully for the exact purpose mentioned here.   At least in driver version 0.1.1 it seemed to work.

However the way I did it was this:

iwpriv wlan0 basic_rates 12
iwpriv wlan0 oper_rates 12

Since the value is a bitmask where 1 = 1mb, 2 = 2mb, 4 = 5.5mb, and 8 = 11mb the setting for just 5.5 and 11 is 8 + 4 = 12

Also since basic_rates must be a subset of oper_rates you have to be careful of the order you set them in or the driver will protest.
