It seems newer kernels changed how they are signing modules and modinfo no longer shows signature information. I ran into this when I went to sign newly built modules and found that all kernel modules (from @module-rebuild) got signed. This is the only reference I could find that explains the issue: https://github.com/coreos/bugs/issues/1054.

If you are, like me, relying on modinfo to figure out if modules need signing, you need to update your procedure. https://wiki.gentoo.org/wiki/Signed_kernel_module_support is slightly outdated in this regard.
