I'll just keep applying the patch, then. :-) It might be an idea to raise this issue with Peter FP Zhang from Lenovo who is actively participating in discussions on the linux thinkpad mailing list. May be, he can ask the right people what command sequence is used by the Windows driver on those newer machines, but then, may be not. Unfortunately, I haven't got the resources to follow up on this right now. Regards, Elias
