As far as I know, it is quite common for a linux user to have an nvidia GPU card.  These cards are really neat.  I was thinking that I could make a Fedora "How-To" for installing the nvidia patch and getting the driver working properly with the 2.6.33 rt kernel.  These are the instructions I used to get it working.  It can be found here  http://forums.fedoraforum.org/showthread.php?p=1383861 at post #14.
(thanks to jerboyd for these steps)Re: Planet CCRMA RT Kernel with Nvidia akmod supporti figured out how to get nvidia going with the official nvidia binary. here goes.

1. download the latest driver for your card from nvidia
2. open a terminal and extract the files from the binary with 'sh NVIDIA(filename).bin -x'
3. cd into the extracted directory
4. place the attached patch into the root of the extracted directory
5. run 'patch -p1 < nvidia_33_rt.patch'
6. if it askes you which file to patch choose kernel/nv-linux.h
7. after this add rdblacklist=nouveau to your /boot/grub/grub.conf
8. reboot into init 3 
9. log in as root
10. cd to the root of the extracted nvidia binary directory and run './nvidia-installer'
11. reboot

we could get this working with the akmod package but i don't know how to patch a source rpm. if anyone knows how to do that please let me know.Attached Filesnvidia_33_rt.patch (1.7 KB, 12 views)take cares,
