The instructions at

	https://wiki.freebsd.org/Graphics

do not mention drm-fbsd<version>-kmod at all. Maybe this was a thing
specific to 12.0? Also the "legacy" / "old" differentiation has been
removed (which is good - drm-kmod metaport containing the whole KMS
driver collection - one package to rule them all).

Also check this list:

	https://wiki.freebsd.org/Graphics/Intel-GPU-Matrix

FreeBSD 11 - 13 should use drm-kmod. But none of the two pages says
if it is okay to use the precompiled version, or if building it
yourself with from your (current?) ports tree is required...
