Typically there'll be a firmware method that provides a mask of the
controlled devices. Do you have the ACPI tables for a device that
implements this? Registering an rfkill interface that claims to only
control wifi but which also kills other devices is likely to confuse
userspace - it would probably be better to avoid registering the rfkill
interface at all in that case.
