I think that it deppends on the way the switch is implemented. On my
laptop, using early 2.6 kernels, the only way I could shut down the
wireless device was using the hardware kill switch, wich I belive may
trigger some interrupt that somehow was caught by the card firmare.
Only with recent firmwares was I able to control the kill switch using
software.

Maybe your switch tuns off the antenna ant tells the OS to turn of the
card, but your driver does not understand it?

I am talking about internal minipci cards of course, when using
external ones, I just unplug it when I have to turn them off!

My knollege of the wireless networking under linux is not as complete
as I would like, so this answer should be taken only as an educated
guess.

Anyway, I find it more important to shutdown the network interface
than to actually turn off the radio interface...
