I think I figured out the problem. It seems Mod2Mask maps to NumLock. If I have NumLock turned on on my keyboard, then unfocused scrolling doesn't work. Do you have NumLock turned on and if so, could you try turning it off and see if it begins to work? If you don't have it turned on, then well, uh, not sure what's going on with your machine.
