I've noticed this behavior on my ThinkPad X60.
* Volume control via the panel icon works.
* Volume control via the hotkeys works.
* These two methods of volume control behave as separate volume control systems in series, eg. if either system is muted, all sound is muted.
* Volume control via hotkeys does NOT result in any on-screen notification.
* On-screen notification does work when I assign volume control to other keys.
The above reason given for disabling volume control buttons due to double-stepping makes sense, but the mute button did not suffer from that problem. When I use my laptop in professional environments it is important for me to know through visual confirmation on the panel icon that the volume is muted. With only a trackpoint mouse, it is also important to me that fast hotkeys are available.
My temporary workaround is to assign Mute to the ThinkVantage key via Gnome's Keyboard Shortcuts window.
