Could you try updating your firmware and see if this problem still persist. Latest firmware can be found here:

As for the dmesg message you see is unrelated. This just an event that the version of thinkpad-acpi in hardy does not know about. Newer versions of thinkpad-acpi kernel module handle this event.
