Not really.  It's super high level and only at the driver level, not
talking about the hardware much.  As far as I can see it's showing a
single physical system and even seems to have what looks like it's
supposed to be two cards connected together which really seems like
it's a single device.

Yes, I'd not expect a separate driver depending on system configuration.
