Change the mouse wheel scrolling acceleration
Hope you're still reading - I highly recommend one of the third party mouse managers like SteerMouse or USB Overdrive or ControllerMate. 

I found the arch of the Magic Mouse just too low and went back to the old reliable Logitech MX Revolution, but I will never install Logitech software again without an excellent reason. These packages will let you configure all of the buttons and SteerMouse (haven't verified for the other two) will definitely let you specify linear or accelerated wheel scrolling with variable degree of acceleration.
