To my experience, the monitor powers down regardless of the screen saver
(as defined in kpowersave, e.g.), at least with TFT displays. You could
consider it a bug that the "blank screen" screensaver does not
immediatly power down the display. I would support that view. ;-)

The energy waste is in the CPU/GPU still working on the graphics even
after the screen has powered off. My guess would be very uneducated, but
I don't think that's very substantial.
