When I made the VNC app I ran into the same problem ozk had.  The NVDI call
to determine the pixel layout is not reliable across all video cards/clones.
I studied his code for a while, and if I recall correctly he done "just
enough" to detect the current crop of clones and the falcon modes. If it
worked on some emulator is was mostly just luck as the screen layout was
stored similarly. Pretty sure that he did not check all possible pixel
layouts, only the ones he directly ran across.  So some hardware could
eventually come that breaks his checks.  Perhaps that's what is going on.

I made a more robust test that checks all 3 RGB positions in all
combinations, regardless if I seen that layout or not.  I discussed it with
ozk at some point and he admitted it was not the most robust test.
