I=E2=80=99ve attached what I think is the correct ports patch for this if y= ou want to build yourself. I don=E2=80=99t know when the package will be updated bu= t it will definitely be before 12 is released. You can also always clone the git repo and build from there for latest version. github.com/freebsddesktop/drm-legacy I don=E2=80=99t have the hardware to test myself so I=E2=80=99d be grateful= if you can give the patch a try and see if firmware loading works.
