Replace the line in your XF86Config  file
Option "Protocol"  "PS2" with
Option "Protocol"  "IMPS2"

and add this line:
Optiont "ZAxisMapping" "4 5"

A WHEELUP action will generate two events,  an SDL_MOUSEDOWN followed by an
SDL_MOUSEUP.
Each time an event happens, you should check if it is a
(event.type == SDL_MOUSEDOWN && event.button.button == SDL_BUTTON_WHELUP)
event.
If it is, then a wheel up action was made.
