The drm-kmod meta-port installs the correct drm-*-kmod for you. It
appears the package installed the legacy kmod. If you want to install
drm-current-kmod or drm-fbsd12.0-kmod you'd need to specify either
instead of drm-kmod.
Does it work? If it works, stay with it.

X loads the correct kernel modules for you. I don't pre-load any drm
modules. I let X handle everything for me. Yours does as well. It
simply works.

The deprecated DRM2 was removed from current after 12 was branched. You
could alter the module_path kenv environment variable to put
/boot/modules before /boot/kernel, but frankly don't mess with it if it
works.

In your case installing the package is a NOP because the base drm is
loaded because it's first in the kld search path. If X works, then
don't worry about it.
