I'll try again.  I've also attached a file containing exactly the same
thing as below (other than the '---') in case my mailer is having
problems.  I just checked that the patch still applies to Linus' tree.

The ThinkPad X200s, like the X61, requires OSI=3DLinux for the mute
button to work.  Without this patch (or the equivalent command-line
parameter), the mute button does not generate a keystroke and,
instead, messes up the sound hardware.

Tested on an X200s.
