I tested the recent versions of the nvidia driver on Fedora 3, and the
one that still works is 7676. All the 8xxx versions after that are
broken. Version 7676 cannot be installed on Fedora 5, because it does
not compile against kernels 2.6.15 and 2.6.16. The solution turned out
to a patch to the driver found here

http://www.nvnews.net/vbulletin/showthread.php?t=66750

After patching, the driver compiles/links against kernel version
2.6.16.

So, for the record: Quadro stereo sync on NV25 and NV28 chips is
broken in driver versions 8174, 8178 and 8756.
