I am a Fedora Core 1 user myself, but I guess the distibutions might be similar. Have you tried to write vncserver :1 in terminal, then open up port 5901 on the firewalls etc, then download realvnc for windows from
www.realvnc.com and connect to your <IP:1> from wherever?
(Then you have to type "gnome-panel" or whatever command launches KDE to see it in realvnc...)
