The same happens with the Thinkpad Edge E220S, in which the F7/8 keys hang the system with x2apic is enabled. When this happens, even the Thinklight stops responding (eventhough it responds during a kernel panic). I suspect that the BIOS just doesn't know how to handle x2apic mode, causing the entire machine to freeze up.
