I use this procedure all the time and it works very well even
over a wireless bridge.
You will need to install an X server on the embedded system.

Subject: [Linux-fbdev-users] virtual frame buffer
I am trying to set up a graphical system on an embedded system with no
video hardware at all. I am using nano-x (http://www.microwindows.com)
The output is into the virtual frame buffer, and then I am trying to use
vnc to remote the display to another computer.
