I won't have the cable for a couple weeks, but I'm also interested in
seeing how it works. I don't have a USB-to-serial device, but I can ask
around and see if anyone I know has one I can borrow.

If you want to send me some modified files to drop in, or even just tell
me what to put where, I'll give it a try. No need to commit it. We might
want to take that off list.

It says they're 16550A's - which is correct. Here's the relevant output.
I don't know what that "Redundant entry" message means; does it mean
anything to you?
