Hi folks,

ThinkPads have hardware volume controls and three buttons to control
them. (These are separate from the standard mixer.) By default,
the buttons are:
- Mute: Mutes the hardware volume control and generates KEY_MUTE.
- Up: Unmutes, generates KEY_VOLUMEUP, and increases volume if
applicable.
