Yes, the iwlwifi driver changes the behaviour (vs. ipw2200) to load the
firmware from pci_probe to network interface open (ifconfig up). It is
expected to support 1) wireless driver buildin kernel (ipw2200 doesn't
support it because network device is initialized before hard disk in
boot up process: no firmware found); 2) saves more power when you load
the module but don't use wireless.
So when the RF kill switch is turned on, the firmware loading is failed.
BTW, we also have patches to delay ipw2100/2200 firmware loading like
this.
Thanks,
