I'm assuming you only want stereo on the CRT since that's what
you have configured.  The XineramaStereoFlipping option described
in NVIDIA's README makes it sound like this setup should be
doable ... I'm not saying you need that option though.

Does glxinfo report that you have a stereo visual?

You might want to test with something simpler like pulsar.

If you post to the NVIDIA forum, then they will want you to
start the X server with -logverbose 5.
