Looks like this depends on a Thinkpad patch you haven't sent yet; did
you mean to?

I've fixed it up by hand and applied both the 1536 and 1557 patches to
my for-linus branch. I'll see if Linus wants to take it before he
releases (doubtful, but it would be nice if these machines just worked
with the new kernel).

Thanks,
