Not sure if there is much to be done as far as the actual buttons clicking but most scrollwheels can be modded. I did it with my old G5, where basically you simply take out a small spring and the wheel spins smooth. No clicks and you can scroll through pages like 20 times faster. The downside being (if you play fps's or other games) is that the wheel has nothing hold its position so it will occasionally move around on its own.
