# yum install vnc-server vnc-ltsp-config

(will install xinetd as a dependency)

# chkconfig xinetd on
# cd /etc/xinetd.d
# vi vncts

The thing you are looking for here, is that each screen resolution you 
wish to support needs its own port number.  No big deal because the file 
is easy to read.

# cd /etc/dgm
# vi custom.conf

----
[daemon]
RemoteGreeter=/usr/libexec/gdmgreeter   #MUST be enabled

[security]
AllowRemoteRoot=true  # does not have to be true -- depends upon your 
usage requirements.
DisallowTCP=false   # MUST be false

[xdmcp]
Enable=true   #MUST be true
----

# killall gdm-binary
# service xinetd start

There are a couple of other changes to make if you do NOT want X started 
on the console, as this simple method wants run level 5 (gdm needs to 
start).

All done!

Things to watch for:

A user running nmap (or any port sniffer) against your server will cause 
the Xvnc server to load once for each open port.  Depending on what else 
is happening, this can cause a usage drain.  If you see a big CPU spike, 
look for allot of orphaned Xvnc processes.  Patches and updates may have 
fixed this simple problem.

Good Luck!
