Applied to linux-next, thanks.

It would be cool if you could figure out a way to avoid having to
continually send these sorts of patches for new chipsets as they come
out.  Maybe for stuff newer than a certain date we can just assume PIIX
style interfaces?  Or maybe there's a way to refactor this even more
cleanly?

Thanks,
