   ## (maybe) NetBSD current, with manual steps
   
      These items do not work in the sense that they simply function after a standard install.  Being listed here implies only that there has been list traffic that implies that after taking a bunch of steps (e.g. new firmware, new dtbs, enabling drivers, applying patches), one can end up with the feature working.  The HOWTO explicitly refrains from describing these steps because they are ephemeral.  However, the fact that list traffic indicates success is possible is a clue that proper support is on the horizon, and that is notable.
