it appears that the Nvidia proprietary driver is necessary.

Frankly the proprietary driver is never up to date with the kernel and
it is well that's luck if it ever works with a new version of the kernel
after you have reinstalled "recompiled the module with code you can't
see against the new code"
If you have a problem with the proprietary driver take it up with
?Nvidia. In theory you pay them to make it work correct ?
If you don't pay them for support then find a card that doesn't use
proprietary code.

Yup, I run the proprietary driver for VDPAU support. If anyone knows
how to get that from the open source driver I would like to know.

The issue with the video card driver is with the vendor of the card.
Since you paid for the video card then you should contact the video card
vendor and have them "fix" what needs fixing. They got your money now
they need to support their products.

An excellent suggestion. The unfortunate reality is that for a least
some of these products, the only well support environment is MS Windows,
sometimes Mac OS X, and only lastly, open systems such as Linux or the
BSD variants. In the case of Nvidia, the CUDA compute engines as well
as the professional switched stereoscopic 3D do have a strong advertised
support for and deployment under enterprise Linux. However, the reality
is that the compatibility with existing Linux environments, e.g., SL, is
not what one might desire for a "supported" product.
However, if enough of us who professionally use SL and other TUV EL
variants sufficiently complain, it is possible that Nvidia will make all
of this work -- provided the profit is there for the corporation.
Unlike SL and related efforts, as far as I can tell, USA for profit
corporations, such as Nvidia, only exist for one purpose -- that all
overarching profit. All else is just lipservice. (This may not be the
case in some EU nations in which for profit corporations are required to
have real workers share in the shaping of policy and in real business
management, unlike the Gompers model in which all the workers are
concerned with are working conditions and financial compensation -- not
the direction or societal value of the corporation.)
The above is not meant as a political statement or a statement of
philosophy -- it is meant purely as a statement of factual reality -- a
reality within which we must work if we want "them to 'fix' what needs
fixing".
