The issue is the way Windows does it is through a userspace daemon.  By
making it OSI=Linux (just as with the Thinkpads currently already in
blacklist.c ..*61 line) the machines just send the OS a key press.

Since newer thinkpads as well as most other OEM machines take this
model. It provides a much better user experience then what it is like
today.

Basically with these machines today you press the mute button:
	- the speakers mute
	- you get no OSD from the OS .. as it has no idea anything has
          happened
	- the headphone jack doesn't mute
