What about this from the man page:

     void VGLSetPalette(byte *red, byte *green, byte *blue)

     This function sets the palette used, the arguments red, green, blue
     should point to byte arrays of 256 positions each.

and

     void VGLSetPaletteIndex(byte color, byte red, byte green, byte blue)

     Set the palette index color to the specified RGB value.

VGL needs a little adjustment to it's keyboard init function to
really support games.  In the raw and code modes the tty code in
the kernel filters out all TABs, 'u's and a couple of others (at
least I think it's the tty.)  I have a few lines of code I put into
doom to make it work under VGL.  Let me know if you are interested.
