Well folks I have some more information and solved it the hard[est] way.
The only thing I found that matches my symptoms pretty closely is in
this blog post http://blog.pdark.de/tag/opengl/
According to the author:
The reason for the error was that the xorg-x11-server contains the
file /usr/lib64/xorg/modules/extensions/libglx.so which is needed for
the NVIDIA <http://www.nvidia.com> driver but the NVIDIA driver has
its own, special version.
The fix for the error was to reinstall the NVIDIA driver again.
Well upgrading the driver (yum upgrade kmod-nvidia nvidia-x11-drv
nvidia-x11-drv-32bit) didn't work. I am now at 310.40 (Thanks Andrew).
Erasing those things and verifying nouveau is blacklisted and
reinstalling them put X in a state where it wouldn't start at all no
matter how many permutations of things I did.
So my solution was to grab some unused disk space and install a fresh
version of 6.3 (6.4 has to wait until the clusters are upgraded). Now
everything works fine (at least for a few hours). Having used Ubuntu,
this was a familiar task and partitioning was set up to mitigate the
headaches.
I still don't really understand my problem, but I do have that directory
available and am willing to help debug, if that will help someone else.
Thanks for the help and support on this.

At the bottom of the SOLVED message, I noted that one program didn't
work. That one is SeeVogh teleconverencing (research.seevogh.org).
Today I discovered a Matlab application (one of mine) that produced
the same symptoms.
To skip to the end: Setting Matlab to use software opengl fixes that
problem.
*Symptoms
*When running a program that encounters this problem, X11 crashes and
the current session logs out bringing you to the login window. All
programs are immediately terminated.
When running NVidia settings from the menu and attempting to check
OpenGL/GLX Information, that program exits immediately.
*Error messages and logs
*Since these programs crash the only information I've found is in
$HOME/.xsession-errors.old and /var/log/Xorg.log.old
The NVidia settings program, .xsession-errors:
Gdk-ERROR **: The program 'nvidia-settings' received an X Window
System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 771 error_code 3 request_code 137 minor_code 4)
(Note to programmers: normally, X errors are reported
asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)
aborting...
Matlab and SeeVogh have:
Window manager warning: gnome-session: Fatal IO error 11 (Resource
temporarily unavailable) on X server :0.0.
/var/log/Xorg.log.old has:

*Request
*I've attached my xorg.conf, which I think is the most probable source
of the problem.
I'd appreciate any suggestions on how to fix this so these programs
can use hardware OpenGL, or how to get everything to use software
OpenGL as a workaround while still being able use the GPU for crunching.
Also any avenues to allow me to dig deeper would help.
Thanks,
Joe

I need some advice on how to turn on RANDR.
I have a few systems with nVidia GPU 5xx and 6xx series. Latest kmod
drivers, multiple monitors with Xinerama enabled.
Newer systems work fine but I have once that been upgraded since before
the 2 were compatible. I have libXrandr installed but it doesn't seem
to be enabled.
[...]
Thank you Florian and Phil. I got it to work. Here's the procedure
I used. I make no claim that it is optimal.
------------------------------------------------------------------------
*Problem*:
When using multiple monitors with nVidia drivers some programs
require RANDR (Resize, rotate, AND, Reflect). If it's not available,
they exit with an error available in $HOME/.xsession-errors or the
terminal window noting RANDR is not available.
If Scientific Linux was upgraded from older versions during which
RANDR and kmod-nvidia were incompatible, it is necessary to "fix"
/etc/xorg.conf.
*Prerequisites*:
My reading suggests that to use RANDR with nVidia drivers those
drivers must be newer than 302.x I am using 310.32, current as of
2013-3-10. I have not verified when this support was added.
The package libXrandr must be installed. I'm using 1.3.0 but have no
idea what the minimum version might be.
*Procedure*:
* Remove /etc/xorg.conf (sudo mv /etc/xorg.conf /etc/xorg.conf.bak)
* Reboot (X will not start) into command line terminal. Or log in
remotely via ssh
* run nvidia-settings with no options. This will create a default
xorg.conf
* reboot (X will start)
* Now run the NVIDIA X Server settings from the System menu, or
nvidia-config-display from the command line.
o On the X-server Display Configuration tab, Configuration
should be TwinView
o As far as I can tell you have to argue with program to
convince it how you want the rest of the options to display.
------------------------------------------------------------------------
I can now run AisleRight Solitaire without going through a VNC server
and for free I can also run my scanner software but I seem to still
have issues with my teleconferencing software but that might be
something else.
Thanks for all your help.
Joe
