Have you tried the 162.50 drivers with the 162.50 stereo drivers? That worked for me. In fact, I now use the 163.71 drivers with the 162.50 stereo drivers and it all runs nice and stable, with a 7950 gt card, crt monitor and eDimensional glasses.
You need to tweak the registry to get the stereo control panel back,
If there is no SedonaDisable key then don't worry about it.
I have a longer article on my experiments with drivers and settings on pre-8000 cards over here: http://www.mtbs3d.com/phpBB/viewtopic.php?f=60&t=2164
