This patch fixes that, along with fixing the declared type of the WWAN kill switch. It also ensures that rfkill interfaces are only registered for hardware that exists.

Please apply to 2.6.27-rc and acpi git. A more complete solution for this laptop will be included in an upcoming patch, hopefully for 2.6.28.
