like cosaides said you did a full install from a none livecd but from a full didstro.
then do a xorgconfig and fill in the blanks. or a xf86config same thing. the other way it to get the nvidia drive from nvidia place it in root. from the login prompt login as root type just like this dir N then push the tab key this will list your driver or any other file that starts with a capital N. then you will ./NVIDIA-Linux-x86-96.43.01-pkg1 then push enter. you need the (./) that is my driver for my card.good luck click type click type.

for opensuse go here:

kernel-PAE-devel is for 64bit installs I believe.
If you have 10.3 one click install is the best option. Otherwise rpm packages offer the benefit of a very easy upgrade for bugfixes in the driver. The shell script Drakeo recommends should work too but upgrading would be difficult as newer versions of the driver appear. Previously, I should have explained that source code from nvidia is not available to compile and if it was I would still opt for a package someone else made.
