I'm still a bit confused.

Suppose I have a laptop with a physical switch marked "radio" which 
tells the OS which position it's in *and does nothing else* (via ACPI or 
whatever) and a radio which has a (pure) software rfkill controller. 
Suppose further that this laptop has a radio button as well.

This would look exactly like my Thinkpad X61s, except that the rfkill 
switch would be connected to the rfkill controller in software, not 
hardware.

I think it would have the exact same problem and the fourth state 
wouldn't help because it would never be any variety of HARD_BLOCKED.
