Does the server really need to display the desktop as well? If not, you would 
be better to set up Xvnc to be run by inetd (or xinetd if you prefer). This 
can be done by adding the following line to /etc/services:

vnc             5900/tcp                        #VNC server

and something like the following line to /etc/inetd.conf:

vnc             stream  tcp     nowait  nobody  /usr/bin/Xtightvnc      
Xtightvnc -inetd -query localhost -once -depth 16 -geometry 1024x768

(That should be be all on one line.)
You will also need to make sure that KDM is configured to allow XDMCP queries 
from localhost. This way, whenever you connect with a VNC viewer, inetd will 
launch a new VNC server displaying a login screen. Multiple users can 
connect, and it should be faster as the server display is not being used.
