for eg, ffb(4), the code in Mesa to implement GL for it
was removed as obsolete and probably a security problem
quite a number of years ago (looks like 2010!)

this can be done, and probably isn't toooo difficult.
anyone wanting to, let us know and we can help with the
details about how drm works and what it needs.
