Something in the X11/extensions/xf86vmode.h functions to load the graphic 
cards gamma table could have been changed?

Having said that, you are aware that loading the gamma table is not yet a 
full colour correction? It's merely a calibration, a way to alter the 
appearance of all desktop elements. Calibration affects gray balance and 
linearity. A ICC conversion with or without calibration is needed to 
obtain colour correction, at least in ICC terminology. I ask this as end 
to end colour management includes many components and your subject line 
sounds a bit irritating.

kind regards
