Hello Karl,

Thanks for chiming in.

Are there recent platforms where these drivers are used? If yes, do you 
know which ones? Or are these drivers useful in old/legacy platforms 
that are still around but perhaps no longer in production?

You suspect there are users for this driver as well?

I was saying I don't see any evidence of recent bug fixes, which would 
make sense if these drivers "just work".
