The 'number of planes' field in the VESAINFO output has nothing to do with 
the number of colors in a certain graphics mode. It only shows the video
memory organization -- i.e. how many different memory locations have to
be touched in order to set a single pixel. The only modes you will find
where this value is != 1 are the 16 color EGA/VGA modes. Try running 
VESAINFO again and check the 'bits per pixel' field in the output. I bet
you will find a few modes where this is 8.
