Ubuntu is easy because they're make it like that for the desktop user and bend-over backwards to do so. Generally, purely FOSS distros don't care for making it easy for binary drivers, they just package them.
openSUSE used to have the NVIDIA driver on their update system, so it was easy to install. I have no idea way they have changed that, but when packages come out for 11.3, it's just a case of 1-click install off the webpage.
You'll just need to wait for the repos to fill up, since 11.3 has only just been released.
I have the NVIDIA proprietary driver installed just fine by the exact instructions I put up, so I can confirm it works. The only down side is that you need to recompile the driver every time Novell updates the kernel.
