For me, the cleaner way is to restart it using the init script of your distro. 
If you kill the X server (or if you log out) a new KDM instance is launched 
using a parent KDM, so, in case of KDM update you can have a parent process 
with a different version than the child one... The parent process is like a 
deamon that start again the child process each time it's terminated or killed 
(and so the X server at the same time if needed).

To restart the deamon (so the parent process):
* on Debian and *Ubuntu: /etc/init.d/kdm restart
* on OpenSuse and Gentoo: /etc/init.d/xdm restart

Don't know for other distro.

Hope I'm clear enough and I've done no mistake ;)
