misunderstood your pb
. so the kernel and glx packs are not installed.
download the .tar.gz version on nvidia official site, and compile them.
tar -zxvf tarfile.tar.gz will extract tarfile in your curent directory
read the readme files in each, i don't remeber which one to make first (think it's glx). you only got to launch make install command in each directory to compile the driver.
move the driver in the right driver directory, and modify the /etc/X11/XF86Config-4 as needed (see affiliated doc in untared packs)
