I think we have discussed this issue before, and if I remember correctly the xorg driver or the xrandr implementation for my ATI Radeon 9200 are broken. This explains why I had put an instance of xcalib before dispwin in an old autostart script I used before I installed gnome-color-manager.
I think that xcalib has a binary blob special ATI gamma loaded driver in it that allows it to work with those cards. Graeme Gill.
