Thanks Sebastian for the great analysis. This is the first I've heard of any of
this.

I note the documentation you linked (version 1.0-9625) looked to be quite old.
This post has driver version information:
https://devtalk.nvidia.com/default/topic/533434/linux/current-graphics-driver-releases/

which states:

"Legacy releases for GeForce 2 through GeForce 4 series GPUs (*)
Current official release: 96.43.23 (x86 / x86_64)
(*) These releases are no longer being maintained."

So that documentation is many years out of date and no longer applies. The
documentation for the latest stable version is here:
http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/index.html

The reason for mentioning all of this is because there does not appear to be
any way to disable TwinView in the current drivers. There is no mention off how
to correct the refresh rate on current releases. I have tried various xorg.conf
settings to disable it anyway, to no avail.

It further confirms that this option has been removed. So it looks like we'll
need to implement a work-around if we ever want this to work under modern
Nvidia hardware.

On a different note, since we're back to this bug ID, I would also like to
point out that the "Broken NVIDIA RandR detected, falling back to RandR 1.0.
Please consider using the Nouveau driver instead." message really needs to be
removed. According to:
http://www.phoronix.com/scan.php?page=news_item&px=Wine-D3D9-Gallium-Nine-Opposed
Stefan Dösinger explained that he does not believe Gallium3D D3D9 is an option
for Wine, and as part of his reasoning for this he basically explained Mesa is
too slow (see points 2 and 4), and implied the Nvidia driver is the best option
for performance right now (in point 3). I don't know if I agree or disagree
with rejecting the D3D9 patches, and I certainly don't want to start a debate
about that here, but having a message in Wine saying you should not use the
"broken" Nvidia drivers appears very contradictory to some of the recent
statements that came out of FOSDEM. :)
