OK - this "magically" started working again, as it did before I upgraded to Karmic months ago. I'm running 2.6.31-11-generic kernel. That was the only real change I can attribute. After rebooting from updating it started working. I did add this to my Xorg, but it didn't work under the old kernel.
What I can say definitely is that with an up to date karmic, running the kernel above, the 185.18.36 nvidia drivers, and the xorg options above, everything works as expected! :-)
