I've used Linux over a similar time period. I remember plenty of times when the scrollwheel wasn't mapped to anything, and I needed to stick a value for ZAxisMapping into the X configuration. At this point, it's been a number of years since I needed to do that manually, but it used to be a pretty regular thing for me.
