6500K
2.2 Gamma
~90 cd/m2
The attached picture shows where the brightness slider needs to be for this particular level of brightness. It's using the 9600M with Auto Brightness Adjustment turned off under Display preferences and Auto Dim off under Energy preferences. I ran the calibration about an hour after I turned the panel on, so it should be reasonably stable.
With this profile, I sacrifice a little contrast on the white end of the scale for better differentiation around the black end, and that's with relatively low levels of ambient light.
This was done with Eye-One Match and an Old Skool GMB Eye-One Photo (predecessor to current i1 Pro spectrophotometer, I think).
