I can live with the switch, just not Ximages.  This is in 24 bit mode, a
mode I don't use because I can only cram 800x600 in 2mb of vram.  I need
my desktop real estate!  :)

No, sorry Houston...  I get ximages mode in 24 bit regardless of the
switch settings. The switches primarily control if the color is correct or
not. 

This is now with the code committed today 4/30.
