The rfkill core has no concept of what the underlying hardware 
implementation is. The fact that you can see the card at all is a bug 
triggered by the fact that we don't currently support PCIe hotplug on 
this type of machine (I've just sent a patch that adds a workaround for 
that), but the inherent reason for it happening this way is because Asus 
implemented it that way in their platform.
