This doesn't quite make sense to me. Pointer acceleration in X isn't a 
client specific function, and the mouse wheel is - ultimately - just 
another pointer axis, with smooth scrolling expressing that properly 
now. Surely with proper mouse wheel axes now, it would simply be a 
matter of letting a pointer acceleration profile be defined for those
