Can display be shared through VNC using xorg vnc module?

[Yuri]

I read here: http://en.gentoo-wiki.com/wiki/X11VNC that in Gentoo xorg 
can load "vnc" module and it will make it also a vnc server.
But I can't find any relevant ports in FreeBSD port tree.
I only found net/x11vnc which is a standalone program that connects to 
xorg server and serves as it's vnc server.

Does this meant that "vnc" module isn't supported on FreeBSD? Or it was 
replaced by x11vnc?
