I saw one once.  It was the console of some hardware I was tasked with
porting NetBSD to.

I ended up going the funky-bus-space route - I created a new bus-space
just for the purpose of attaching the console com instance to.  Worked
fine, once I figured out enough of the bus-space paradigm to get it
right. :)  (No, the port never went live.  The project was canned, and
I don't think I even have any of the code any longer.)
