At the moment the drivers have to do the conversion before calling 
xf86PostMotionEvent(). But as soon as I've done some more testing I'll start 
pushing patches from bug 10324 into master, and then this conversion should 
not be needed anymore.

That would probably have been a good idea when the XInput version was stepped. 
For now I think the drivers have been corrected and I'd rather leave it as it 
is and do the cleanup when the version is stepped again for another reason.
