I've update Debian 6.0.4 to 6.0.5, update all packages and remove everything 
I've made from my previous test. 

I've continue my tests and I've got an issue with active stereo. Previously, 
I've got tested active stereo with the stable release.  

On unstable version, only the right eye is render (OGLplane and Virtools demos).
Quad buffer is on, everything seems to be setup as usual for active stereo. 
I've tried with and without the S400 card.

I will try to gather more informations about this.
