Yeah, it's just us enthusiasts who maintain the old chips. It's nice, because
since they don't have very shiny new features, it is often a bliss to add
proper kernel support these days since the subsystems improved and
they become very good proofs of concept.

I'd be delighted to have a look! I hope my mailbox survives that, otherise
sharing it on Google drive works fine.
