Thanks Ralf, helpful info. But no luck yet. see below.

Don't guess, take a look at /var/log/Xorg.0.log. When doing this, first
grep EE, IOW run
grep EE /var/log/Xorg.0.log
Failed to load module :)
grep EE /var/log/Xorg.0.log

Modules have to fit to the kernel. You should run the NVIDIA *run thingy
manually.
I've got no time to search for you an English howto, sorry, on the quick
I only found a German howto:

ok. that clarifies it, thank you.
Anyway, I tried the module building only, and failed again.
