Gamma control with Intel Graphics Media Acc vs Adobe Gamma

[pinerd]

My T61 currently uses the Intel Graphics Media Accelerator Driver to control gamma, brightness and contrast. However, it's still too white/bright. The gamma is currently set at 1.0 in the software and won't go lower.

However, when I use the Adobe Gamma calibrator, it can lower the Gamma down more and the screen looks much richer and not washed out. Unfortunately, everytime I reset the computer, it goes back to the Intel Driver settings.

Is there a way I can turn the Intel drivers off and use only Adobe? Or lower the gamma more some other way?
