I am using mode 24 and 23. Mode 24 works o.k. My program uses egacolor 9
(light blue) which does not seem to be changed, egacolor 10 (light green)
which becomes a dark green with mode 23 and egacolor 12 (light red) which
turns into something very light blue (almost white - definitely lighter
than ligth blue) in mode 23.

I own a LCD-Panel, most of the VGA modes do not work with my panel.
VESA does not display mode 23.

vgatest uses setegacolors and displays exactly the same behaviour.
I think it might be a very special problem related to the properties
of the Riva128 card which does not support 16 bpp modes properly.
