Yes new TPs X201, T410, T410s, Tt10, W510, & W710. Will need alsa
backports for Doc Mic support & microphone jack support to work. This
way they can get Ubuntu Certified. 

Also the hw mixer does work without this.. This is trying to unify it
(I'm even saying upstream to remove it) .. but this work isn't complete.
Does not turn the hw mixer on in most newer Thinkpads.

Also the hw mixer only mutes the speakers & not the headphone jack.
