the answer is a bit late but maybe helful for someone, who knows.
The question is: do you really need a Linux VNC server?
On non-LTSP, non-Unix machines you can also use X:
http://www.bn-paf.de/k12ltsp/tips.html#x

I guess you've been doing it with K12LTSP servers before.

For standard Linux servers you need:
- in addition to vnc-server the RPM
ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/2.1.0/i386/RedHat/RPMS/vnc-ltsp-config-0.0.1-1.noarch.rpm
It must have been included in the K12LTSP 2.0.X vnc-server RPM but is
now separate.
It basically adds some lines to /etc/services and creates 
/etc/xinetd.d/vnc
- afaik the server must be in runlevel 5 (just type "runlevel" to see)
- afaik the server must have xdmcp enabled
- server shutdown should be disabled in GDM (all users could do it
then!)

The faq entry from http://www.bn-paf.de/k12ltsp/tips.html#vnc ->

Q: If no X server is installed on the client, how do i connect using
TightVNC?

A: Connect using the following ports (see /etc/services):

vncviewer 192.168.0.254:0 (= 1024x768x16)
vncviewer 192.168.0.254:1 (= 800x600x16)
vncviewer 192.168.0.254:2 (= 640x480x16)
vncviewer 192.168.0.254:3 (= 1024x768x8)
vncviewer 192.168.0.254:4 (= 800x600x8)
vncviewer 192.168.0.254:5 (= 640x480x8)
In K12LTSP <2.1 this was :5X instead of :X!
LTSP and VNC contrasted [http://www.ltsp.org/contrib/ltspvnc.html] (and
why you should probably be using both)
As X is considerably faster you should use that instead if possible!!
