I am not sure about that. The colors with 2.6.18 are better than with  
current but still not quite what I would expect. Perhaps there are  
just not enough colors or perhaps the 2.6.18 default colormap is  
closer to what X would want to set.

Also when I kill the X server with Ctrl+Alt+<- the colors seem  
momentarily corrected before the X picture is cleared ;-)
