Good news,
I just got my CF634 working on my Windows 2003 server!
If you download the drivers for XP (R9052154) from the URL in my last message and use them to install the display, then it works. It seems that it is only the custom made drivers from CrystalFontz that does not work. Hopefully some one from CrystalFontz reads this and fix the drivers to next release.
Good luck!

EDIT: The Config program reports the service as not started when it is in fact running and trying to start the service from the config program results in a error. But the service is running fine and to start and stop the service just use the Services applet.
EDIT 2006-06-05: The icon in systray works fine when logged on to console not in a remote desktop session. I've upgraded to latest public release and it works like a charm.
