Roger, I don't think you're going to get this to work easily. VNC on 
Linux works by implenting an Xserver, and X and vgalib are alternate, 
competeing ways of controlling a graphical display under Linux.

If somebody knows a way to make a VNC server that intercepts vgalib 
calls and does the appropriate VNC framebuffer things, my hat's off to 
them. It's certainly theoretically possible, and VNC servers have been 
implemented for all kinds of odd things (would you beleive a toaster?) 
the core protocols are pretty simple.

Apparently a similar undertaking is offered to students taking
CS 378: Linux Kernel Programming as a possible final project for the 
course. See choice 4 at

I don't think this will be an easy job. There has been some work done on 
a svgalib port of vncviewer, but unfortunately that's not what you need.
