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.
