After a bit of work, on-line research (not entirely from the Nvidia site 
nor Nvidia documentation), I have modified the Nvidia application 
created xorg.conf file to one that actually works:  a stereo 3D 
application such as UCSF Chimera actually activates the 3D functionality 
under SL 6x that works.

For reference, below is the content of a working Nvidia driver (not 
noveau) xorg.conf (obviously, the specific Nvidia board as well as the 
specific 3D display monitor may change):

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 310.32
