The point of that discussion was that there's nothing wrong with the driver. It is the highly modified linux kernel included in Fedora core 4 that's the problem. Redhat has always had a nasty habit of patching the linux kernel in ways that will cause the Nvidia driver and other 3rd party drivers to break.
If you want my advice, use a distro that contains a completely unmodified linux kernel ( a vanilla kernel as it is called
)such as Slackware. You can of course download the vanilla kernel source from here
www.kernel.org and build it from scratch too.
