As there are no probes supported with linux for the moment, there is no  
real way to calibrate a monitor.

Two important things are to be taken in account :
1 - Does the colour management has to be done in a desktop-wide way or  
in an application-wide way?
2 - If you use a CRT, gamma makes (some) sense. If uour are using a  
LCD/TFT, there is no real meaning for "gamma" and it would probably  
tricky to "calibrate" a display without an appropriate tool

If the display is not calibrated all what can be done is switching from  
a theoretical colour space to an other theoretical.

The scarse[1] project was very interesting but this project is in a  
dead state and the monitor problem has no been solved in an other way  
than giving Trinitro (or what you want) theoretical icc profiles for a  
given colour temperature.
