Woah! That worked *perfectly*. Super thanks! (It took quite a bit of
searching to figure out B43_RFKILL. There's no kernel prompt for it.
Once I grepped through, enabling INPUT_POLLDEV set this option).

Thanks! It works great now!!

My bandwidth isn't really that much of an issue, since at home my WiFi
is a lot faster than my download speed or the speed of my NAS server.
Good bye ndiswrapper ... :)
