I am having the same problem -- XFCE or Gnome will correctly turn my backlight off, but KDE will not. This started with KDE4; KDE3 used to work fine. I'm using a Dell Vostro 1400 with the Nvidia 8400 card. Doesn't matter whether I use the proprietary Nvidia driver or the VESA driver (same result). xset -q shows:

DPMS (Energy Star):
  Standby: 0 Suspend: 0 Off: 600
  DPMS is Enabled
  Monitor is On

So oddly it looks like KDE is setting X correctly. Let me know if other info would be helpful.
