I followed the instructions here: http://ubuntuforums.org/showthread.php?t=517156 and can confirm that the touchpad including scrolling, left- and middle-click and the media keys work on my 5920.
I know no easier way and it is definitely worth the effort.
The only problem I am still having is the sensitivity of the touchpad which is too low for my taste. I often need a second or even third click to get the desired action.
