There's a number of places this can be controlled.  The setting is really 
an xorg setting, so it can be set in xorg.conf, if you have one, and 
there's probably some default for those that don't.  For on-demand 
setting, xset (run in a konsole or other terminal window) is the xorg 
solution.  Run it with no parameters to have it spit out the possible 
parameters, or with q, to have it spit out current settings.  You'll be 
looking at/for the dpms settings.  Of course, you can setup an xset script 
to run at kde start, if desired.

In kde, I think it's power-devil that sets that.  But on Gentoo, that's a 
USE flag, IIRC, so you may not have it or the associated kcontrol module.  
You can check in kcontrol, under advanced user settings, hardware, and see 
if power-devil is listed.  Here, all I have is hal listed, but I 
purposefully didn't merge power-devil, etc.  And I don't have screensavers 
merged either, which might have the setting as well.  Anyway, I don't see 
a GUI way to set display standby and power-off settings.
