Yeah, I'm aware that it is still current despite the archaic packages - if it 
weren't we would probably have dropped it already, at least for encode.

I'm not sure that's quite accurate - if you install on current hardware it will 
refuse to run at all because that version of the driver doesn't support 
anything newer than Haswell :P

But yes, it should definitely be fixed somehow.  At some point that "fix" is to 
drop support for it, though.
