A quick-and-dirty fix would be to simply launch something like "kdesu kcmshell4 
kdm" from the kdm settings dialog if we are not root:

#include <QProcess>
        if (geteuid() != 0) {
                // launch kdesu, workaround until KDE 4.5 for debian bugs 
523094 536441 546376 575746 580269 602976
                QProcess kdesu_process;
                
kdesu_process.startDetached("/usr/lib/kde4/libexec/kdesu",QStringList("/usr/share/kde4/apps/kdm/kdmconfig_root.sh"));
        }

content of /usr/share/kde4/apps/kdm/kdmconfig_root.sh:
#!/bin/sh
[ $(id -u) -eq 0 ] && kcmshell4 kdm

The id check is necessary because if a user presses the ignore button another 
kdm-settings would be launched which asks him for the root password again.

Code status: This code is not yet tested inside kdm-config, only inside a demo 
qt application, because I have no experience with patching and building kdm. If 
you think it is good I can test it further. The shell script was tested as root 
and non-root with dash and bash.
I tagged this "patch" because it is probably only a few lines away from being a 
real patch. If you think the tagging is wrong, please remove it.

This solution would, in contrast to adding a button or message box, not require 
any locale changes.

Thanks for any feedback
