I can suspend with gnome-power-manager. But when I resume from suspend, the color is not correct,maybe does not have enough bits deep. when I resume from hibernate with gnome-power-manager,the color is correct. thanks

after I update kernel 2.6.30-r5 to 2.6.31-r6, the color is right after resume from suspend.
