Comment 34 for bug 61827

As far as I know the 7440 rfkill hardware is different from anything supported in the kernel, including anything to do with the 7400. The fsam7440 module above isn't integrated into the kernel's rfkill subsystem so I don't think it'd be accepted upstream. Looking at that module, the actual code to turn wifi off and on is trivial, but it needs someone schooled in the ways of the kernel rfkill subsystem to get it integrated.
