Doing the right thing sounds good! Of course this would require to install a 
file in /usr/lib/pm-utils/sleep.d, but that should be all. The dbus message is 
sent by pm-action, which is running on behalf of hal.

Is it a problem for KDE to install such a file?

I'm not very familliar with dbus, but i understand that a dbus message can be 
a signal that anyone can connect to. So if the signal is sent, any application 
or applet should be able to catch it?
