I have two servers at the lab which at the moment are causeing me a real headache. One is Suse 9.3 the other 10.0. I have removed Kpowersave due to them freezeing if they are left in KDE and logged in. So to be safe I have stopped the Kpowersave deamon.
On my laptop I also get the same error message taht you are getting
"powersave daemon is not running... (etc)"
I'm interested because not all too long ago I noticed a Kpowersave update via YaST. I'm not sure but I think that they maybe a bug in the deamon.
