Just prevent the module from loading, or make sure the radio doesn't turn
on.  The radio itself accounts for somewhere between 100 mA to 300 mA
depending on the brand and model.  It's not much - 1 W to 3W maybe.  Power
consumption really goes up when the radio is hunting and trying to connect
- looking for APs.  once it's connected it drops.
