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.
