rfkill isn't a generator of events, it's a consumer. The problem with 
EVIOCGRAB is that it also prevents in-kernel consumers of input events 
from receiving them. That includes the console layer, but it also 
includes the mouse emulation and KEY_RADIO->radio off functionality. So 
using EVIOCGRAB really isn't an option, and we need some other way of 
handling the problems that that causes.
