[Bug 182716] Re: bcm4306, bcm4309, bcm4311, bcm4312 with b43 : Authentication with AP doesn't work.

Hi Ben,

I've encountered the same problem with the radio hotkey not being recognised (although I use ndiswrapper not b43). I believe this occurs if the device is not active during boot, it appears as though X (which controls inputs such as this) does not realise the key should do anything unless the device tells it that it should (or some such). I believe you can send the same trigger to the kernel, however, by altering a file in /proc. Unfortunately I'm not sure what it is, as I've disabled the hotkey in my bios (which is your second option for getting around this). If you want to try the first option, try:
tree -f /proc | grep rfkill
It should be called rfkill, or rfkill_enable, if what I recall is correct. Then try using 'cat' to read the file (you'll probably have to do this as root), you'll get a binary value in return, 'echo' the opposite value into the file and see what happens.
