Here's the tutorial:

This is a Three-Step Process. If you don't follow all three steps, your install will fail!




1. Install the nvidia driver. ( if you have 4Gb of RAM or more you will probably have a PAE kernel [32bit only] so follow the PAE part )

For GeForce 6, 7, 8, 9, 200 & 300 series cards

Code:
su
rpm -Uvh   http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm     http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
yum install kmod-nvidia  xorg-x11-drv-nvidia-libs.i686
If you use a PAE kernel

Code:
su
rpm -Uvh   http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm     http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
yum install  kmod-nvidia-PAE
Or (akmod builds the required kmod on bootup )

Code:
su
rpm -Uvh   http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm     http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
yum install akmod-nvidia  xorg-x11-drv-nvidia-libs.i686


2. Edit grub.conf ( if you omit this step the driver will fail to work )


this command adds rdblacklist=nouveau option to /boot/grub/grub.conf

Code:
su -
sed -i '/root=/s|$| rdblacklist=nouveau|' /boot/grub/grub.conf
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname   -r)-nouveau.img
dracut /boot/initramfs-$(uname -r).img $(uname -r)
3. Reboot
And this is what I did:

First I executed the following commands:

Code:
su
rpm -Uvh   http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm     http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
yum install kmod-nvidia  xorg-x11-drv-nvidia-libs.i686
Then In step 2 I executed the following commands:

First:
Code:
sed -i '/root=/s|$| rdblacklist=nouveau|' /boot/grub/grub.conf
Then this one:
Code:
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname   -r)-nouveau.img
And when I got to this one:
Code:
dracut /boot/initramfs-$(uname -r).img $(uname -r)
I got this message: Will not override existing initramfs (/boot/initramfs-2.6.33.3-85.fc13.x86_64.img) without --force
So I kinda ignored that command and restarted my computer and that's when I received this message:

============= I used a FedoraDVD/Rescue Option to access my system:

Here's my grub.conf file (boot/grub/grub.conf):

When I execute the command: uname -a I get the following:

I've never used anything that changed the initramfs. This works fine for me :
http://rpmfusion.org/Howto/nVidia

Notice it says "you either need to recreate the initrd manually after the driver has been installed, or add a command line option to the kernel."

I have only ever added the options to the kernel line in grub.conf
I suggest deleting the currently existing initramfs created by dracut, then renaming the backup initramfs back again
Code:
mv /boot/initramfs-$(uname -r)-nouveau.img /boot/initramfs-$(uname -r).img
But check to see if the backup file exists first !
