acer-wmi is indiscriminately using the device state from hotkey events to update the various rfkill states. On the Aspire 1830 this can result in a soft block on the wlan when the touchpad hotkey is pressed, as it is reporting a non-zero device state that does not reflect the wireless status. To fix this, only update rfkill states when a wlan or bluetooth hotkey is pressed.
