this is the biggest problem I have, would be very nice to get to the
bottom of it! anything I can do to check what happens? I have the newest
ati-drivers and a "more-than-good-enough" for quake2 card.

hwgamma solution is much prettier. It's easy to see, just change between
glx and sdl, you'll see the difference in color right away.
