Don't know if this will help or in fact it is what you really want to do:
  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.

  Good luck.

Reply-To: linux-fbdev-users@lists.sourceforge.net

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.
