Re comment 3

Installed the new X driver on a Plasma partition on this machine.  That worked fine and so did reducing the screen resolution via nvidia-settings; not nice but it worked.

Back to the original partition and rebooted to the server kernel.  Everything OK there as well.  The kmod was generated during the boot sequence.

Thank you Len & James for the tests. Since few people use this package, and x64 (the normal case) has been diversely covered, I think OKs are well justified.
