Right, it's udev, not the kernel. And things work as expected. It's just
unfortunate, that it does not work for ordinary users who log in. All other
use cases for on-demand module-loading are covered, needed, and will work
fine.

Hmm, that's pretty actionable, isn't it?

It tells you that you don't have the permission to open the node. Just
throwing a 'sudo' in front, which gets the permissions, would have made
everything work.

Btw, future versions of systemd will also handle logged-in users ACLs:
