Wheel handling in cocoa.m and in monitor.c may supply a delta greater than 1 for the mouse wheels. Those front-ends would have to translate those deltas into a series of press+release events. Then the emulated devices (at least the PS/2 and USB devices) would have to sum the designated button presses for outputting again as wheel data. If that's the way we want to go, I can rework the patch easily enough.
