First, I need to know some details about the B43 hardware, to help with this. 1. It has an input pin that sometimes people connect buttons/switches to. Does that input pin act as an input for a FLIP-FLOP (and that flip-flop output is the hardware rfkill line), or is it the hardware rfkill line itself? input for a flip-flop means it toggles the kill/unkill behaviour when the input pin detects an edge (press/release of a button). direct hardware rfkill line means you need a SWITCH in that pin, because it directly sets the state. If the pin is active, the hardware rfkill line is active. If the pin is inactive, the hardware rfkill line is inactive. -- "One disk to rule them all, One disk to find them.
