Oh, well, yes...
AFAICT, VNC needs either X running to provide a virtual framebuffer, or
a physical framebuffer....
I tried using the kernel virtual framebuffer, but basically it is just a
graphical bitbucket.
If you're a framebuffer hacker I am told it is not difficult to
implement a full virtual framebuffer in the kernel... But I looked at
the code and it was not at all obvious to me what was going on.
Briefly, you have to allocate some real memory, and then set up the
frambuffer functions accordingly. We ended up not using nano-X, so I
dropped the whole thing.

Not sure what you mean. I don't think VNC allows you to zoom; I could
be wrong....
