I recall by head the existing of a vnc-server that copies the framebuffer 
device. Try a search for 'framebuffer' at 
http://www.realvnc.com/swish-e/search/vnc-list (or google for it)...

(I found http://www.hexonet.de/software/x0rfbserver/ which does not show what I 
expected...).

Definitly not. Xvnc just stands for an X11-server with a VNC backend (and no use 
of display hardware). It IS an X11-server.

I have some headless machines (no display, text-only console) that serve some 
vnc-sessions as described on 
http://www.sourcecodecorner.com/articles/vnc/linux.asp. That does nothing with 
the framebuffer or what ever is on the console.

No, as above, Xvnc includes an X11 server. You can replace your call to an 
X-server on your system to use Xvnc and have that operational.

On some RedHat systems, I edited /etc/X11/gdm/gdm.conf to start Xvnc and not 
XF86. It gives a text-console and display :0 is at `vncviewer:0`. Be sure to add 
the vnc-specific options to the Xvnc-line. See `Xvnc --help` for a list.

With some sys-admin knowledge, the mentioned settings can be setup on HP-UX, 
Solaris and many other unix implementations.
