I got my Nvidia card installed correctly by following these instructions
at rpmfusion:
Fedora 10 and 11
Please remember that once the drivers are installed, they will configure
your xorg.conf automatically and changes will take effect after a full
reboot. There is no need to run nvidia-xconfig or other tools.
GeForce 6 and higher (mine is a 9400 GT)
yum install kmod-nvidia
Fedora 11 and nouveau
As nouveau is enabled by default starting with Fedora 11, you may
experience problem which is caused by the nouveau kernel module being
present in the initrd image. To avoid such problem, after you have
installed the right series of the nvidia driver for your hardware, execute
the following commands:
su -
mv /boot/initrd-$(uname -r).img /boot/initrd-$(uname -r)-nouveau.img
mkinitrd /boot/initrd-$(uname -r).img $(uname -r)
reboot

----------------------------------
Before reboot, the following command:
lsmod | grep nouveau
has this output (at least for teh 9400 GT card):
nouveau 472800 0
drm 208060 1 nouveau
i2c_algo_bit 6020 1 nouveau
i2c_core 22288 5 nvidia,i2c_piix4,nouveau,drm,i2c_algo_bit
After reboot, there is no output whereas:
lsmod | grep nvidia
gives:
nvidia 10260024 26
i2c_core 22240 2 i2c_piix4,nvidia
The Nvidia driver is installed!
