Easy way to make this "just work" is to add drm-fbsd12.0-kmod to
PORTS_MODULES in /etc/src.conf. This probably should also be done for lsof
and virtualbox-osf-kmod, as well, as both depend on unstable KBIs. I have:
PORTS_MODULES= emulators/virtualbox-ose-kmod
PORTS_MODULES+= sysutils/lsof
PORTS_MODULES+= graphics/drm-kmod (or the appropriate port for your system)
PORTS_MODULES+= graphics/gpu-firmware-kmod

Ports listed in PORTS_MODULES are always rebuilt with kernel builds.

I'll also mention that drm-kmod is just a wrapper that picks the correct
port for your version of FreeBSD. If you install drm-kmod, you will see boh
that port and the "real" drm-*-kmod port is installed.
