When running the commands (sudo iwconfig wlan0 power on/sudo iwconfig
wlan0 power off) with Natty's default drivers, they complete
successfully without anything being displayed on the screen (I didn't
try iwconfig); however, when I run them with the latest wireless driver,
I get the following outputs:
$ sudo iwconfig wlan0 power off
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.
$ sudo iwconfig wlan0 power on
Error for wireless request "Set Power Management" (8B2D) :
GET failed on device wlan0 ; Operation not supported.
$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

I'm not sure how to tell if power saving is on or off, I would guess it
probably isn't on with the new drivers.
