No, it can't be ifconfig'd up. The driver doesn't allow it
in the wpi case (I haven't looked at other drivers).

Note that I don't know if the button really does prevent the wifi
from working. It could just be a button connected to a gpio pin, and
everything is handled in software (again for wpi I guess it really
turns the radio off, because button status is reported by the adapter's
firmware. For e.g. athn it may just be a gpio pin).
