Ah.  That makes sense, but certainly appears to be incompatible with the
assumptions Xsun24 is making.  Which means I have to rewrite the
pixel-drawing operations within Xsun24, I presume?

I got a kick out of the combinations that actually did work:

#define RED 	0x00FFFF00
#define GREEN 	0x00FF00FF
#define BLUE 	0x0000FFFF

So it's sort of a backwards masked map.  I take it this is an unusual
piece of hardware?  I wonder if the RAMDAC or whatever is programmable
to allow me to change this...
