going on when you deactivate the radio kill switch?

It's all done behind the scenes I think (it's an ipw2200 device). There's
no rfkill integration from that driver.

And rfkill-input will soon be enhanced to let the user configure it to do
something different if he wants. Your driver doesn't (and shouldn't)
hardcode policy about it.

Ok, that makes things much easier for me :-) But it means that for now the
user will have to manually kick the device.


Thanks. Please take note that rfkill will, right now, try to BLOCK all
radios on suspend. That will be changed soon (2.6.28 at the latest), and
your driver will have to handle blocking radios on suspend directly if it is
needed for toshibas.

Why is this necessary? Doesn't the radio power down as part of the suspend
process? How would I tell what the hardware is doing?

I'll update the diff when I can.
