absoultly not, the GPL forbids it, who ever owns suse. All that is wrong is the NVIDIA prebuilt modules only work with the *release* kernel, not updated ones. Grab the suse kernel sources from YaST2, and the real nvidia driver (not the suse one) and it will build the required module for you.
Edit: Sorry if you already have the kernel sources read the --help with the nvidia installer and manually point it to your sources. If that doesn't work recompile the kernel and then install
