I've seen this as well, but only *before* I log into KDE.  If I boot the 
machine into X and leave it at the kdm login window, it will black the 
screen after a while (no idea how long as I usually login promptly). 
Once in KDE my screensaver kicks off after 10 minutes of idleness as it 
should; there is no black screen.
