I remember having exactly the same problems after the module was finally compiled. I then used a HOWTO on the suse ftp to configure the kernel. I found it again, here is the link:
Hope that helps.
The important part of this document for SuSE 8.2:
1) Kernel sources must be installed and configured. Usually this means
installing the 'kernel-source' RPM with YaST2 and configure it then
with the following commands:
cp /boot/vmlinuz.config /usr/src/linux/.config
cp /boot/vmlinuz.version.h /usr/src/linux/include/linux
cp /boot/vmlinuz.autoconf.h /usr/src/linux/include/linux
make cloneconfig dep
2) Use the nvidia installer.
3) Enable 3D support with SaX2.
