Initial port for a drm-legacy-kmod port. Probably version check should be changed if base drm1/drm2 legacy bits are dropped.
Unit Tests Skipped
The one thing I would say, however, is I'm looking forward to the metaport that will assume the name of drm-kmod and will do the right thing for users based on their architecture. I know that's next, I'm just stating the obvious for future onlookers.
