But that would mean changing the frequency of the events, correct?
For every small wheel delta a new event has to be sent. Can current software 
cope with that? I'd expect that it starts scrolling wildly ;-)

The problem is not with large deltas (which are thrown away in the current OSX 
version, if I understand the patch correctly), but with small deltas, which 
get emitted from Xorg with a pretty high frequency.
