Hi, folks,
Well, still more fun (for values of fun approaching zero):
1. Went to install CUDA 9.0... well, gee, there is *no* CUDA 9.0.
Even though I installed the 9 repo, all that I get is 8. I've
used their webform, and an waiting on a reply.
2. I remove all nvidia packages.
3. It appears that the kmod-nvidia is what I need; that's what
nvidia-detect says. So I try to install... bzzt, thank you
for playing.

Well, no it's not complete, and it's trying to install in the *previous*
kernel, not the running one.

kmod packages are a special class of package on RHEL that take advantage
of the stable kernel ABI in Red Hat Enterprise Linux. When a kmod
package is compiled against a kernel, the kernel module will be
installed for that kernel and the weak-modules script will then weak
link the module against all other kABI-compatible kernels installed on
the system. This means that you do not need to rebuild the kernel module
for each and every kernel update (or worse, delay updating your kernel
whilst you wait for me to rebuild the module for you).
So yes, the module will likely be installed against a previous kernel,
and maybe one that isn't even installed on your system. But it will weak
link against your current kernel(s) providing none of the kernel symbols
used by the module have changed between the kernel the module was built
against and the current kernel in question. If you don't understand,
just think of it as magic and be grateful you are running an Enterprise
Linux kernel and not a fedora kernel.
As to the earlier error messages, have you been playing with depmod?
Where is your modules.dep for your installed kernels? Anyway, the magic
described above has likely not worked correctly due to missing
modules.dep, so I would uninstall the nvidia packages, sort out your
kernel(s) / depmod information and try again once you have a sane system.
