I use a Lenovo Thinkpad X200s with the 2.6.32-22-generic i686 Kernel.
On my external Thinkpad Keyboard, the button does work. On the laptop itself, it doesn't. No matter if headphones/ext. speakers are connected via the headphone jack. The "mute" button on the machine does not work.

I hope this helps to solve this little problem.
