I wouldn't mind using 100.14.11, but it does not play well with Compiz
and crashes the entire system as I described above, unless that has been
resolved recently. There is a thread on an OpenSUSE list/message board
that describes getting the NVidia driver to compile on a Xen kernel. In
it, it also further says that Livna has built the fix into their
package. I am assuming that Matthias did the same for FreshRPMS,
because it works.
While looking for the thread, I found this in the OpenSUSE wiki
( http://en.opensuse.org/Use_Nvidia_driver_with_Xen ). The driver
version referenced is 9631, and the patch is from www.nvnews.net. I
know NVidia has been working on Xen compatibility for a while now
(sometime 2005). BTW, no mention of Xen at all in the 9762 version of
README.txt.
Any Xen support added by 3rd parties is not supported. Or more
accurately, you should contact whomever provided you with a custom
driver package for assistance. I should note that any Xen support
added to these 3rd party packages is not going to be sufficient for
most rigorous use cases. Where did you read that NVIDIA was working
on Xen support since 2005?
I was mistaken when I stated that the driver README documented the
lack of Xen support, however I'm telling you that its not supported.
It is documented here, however:

If you're having composite problems with 100.14.11, you should report
them here after reading all the forum sticky posts:
