Shame, I just noticed your mail now after I investigated the code  
myself!  I  didn't investigate as thoroughly as you did, but I guessed  
that that was where the problem was by comparing the old (pre-3.1.2)  
and new (vboxmouse_15-based) drivers, and I just copied and pasted the  
code from the old driver which also does the scaling manually.  My  
fault for wanting to be too clever in my earlier fix and make working  
code "nicer" by calling the official helper function...
