Well, that explains why vncserver won't work right.  It gives me hope 
that everything else I've done works.

OK, I've had a look at the various kernel source xxfb_mmap functions...  
If I were to try and write one for the vfb, where do I find some docs or 
info on where to start?

And/or what's the closest one I can copy from driver/video?  Is there 
one that is simple and well documented which explains what xxfb_mmap is 
supposed to do and how?
