This is 
http://mail.kde.org/pipermail/unassigned-bugs/2010-December/016850.html 
from almost two years ago.  The tunable had been on the feature removal 
schedule for two years and would have emitted a warning if you had run on 
any kernel during that time.  KDE 4.6.1 and later from two years ago work 
fine.

Fixed in udev v162 at the same time kde was.
