Thanks for reporting and contributing. Apparently we cannot tell the driver to use a certain power level when the hardware is disabled... This is a shame, because the power level will be incorrect when the device is re-enabled -- laptop mode tools doesn't re-apply settings when interfaces are enabled or disabled. I wonder, does this problem happen only when the hardware kill switch is used? Or does this already go wrong if you just do an ifdown on your device (as indicated by /sys/class/net/$DEVICE/operstate)? I wonder if there are other things that can't be used if the device's radio is killed. Might be worth a submitting a bug report to the iwl guys...
