I don't know how 200 mW cards differ from others as far as driver interfaces are concerned. However, I would tend to believe that the TX power can be returned to the previous value after turning it down since the driver just has a simple mapping between the full range of BBP register and selected range of values from iwconfig. The values won't be accurate (well, they aren't even for 100 mW cards), but smaller value should always mean smaller TX power and largest TX power value from iwconfig should map to largest value for BBP's TX power configuration.
