using PowerDevil in other desktop environments

[Guest]

I am a big fan of KDE applications, but I generally prefer to use another desktop environment. Specifically, I use ion3 as a window manager and no desktop manager. But, nothing about this post is specific to ion3. It would hold for any session besides KDE that one starts from kdm.

I would like to be able to use KPackageKit and PowerDevil from this other environment. Right now, I can run

kdeinit4 +ksmserver

from the command-line. But, there are two problems with this. First, it doesn't start PowerDevil, although it does start KPackageKit. Second, it launches the Desktop,

/usr/lib/libkdeinit4_plasma-desktop.so

Of course, I can then manually start PowerDevil from the System Settings panel, and I can close the Desktop. But, I would like this to be automatic.

What I imagine to be the correct behavior is to run

kdeinit4 +kded_kpackagekitd.so +kded_powerdevil.so

But, this terminates with an error:

varanir /usr/lib/kde4: kdeinit4 +kded_powerdevil.so +kded_kpackagekitd.so

I've looked around on google, but I cannot figure out what to do about this.

Short version of question: how to I use KPackageKit and PowerDevil outside of KDE?

Background: I am running kubuntu-9.10 on x32.
