I'm curious, can you provide a PCB picture for the video block?
Cyber9385 is the very same chip used by a bunch of PC-9821 notebooks too, and there's a PCI card on VGA Legacy MK-3 that clearly shows a VGA BIOS, however I don't think there's one here unless integrated in the packaging?

I don't think I like the driver naming direction this is taking off.
I gave a glance at ref catalogs, everything between 200 and 799 uses an Intel CPU (jumping between ISA/MCA and then PCI), and I believe the IBM classification has more to do with form factors than anything else.

As an example: the ThinkPad 760XD maps a 82430MX PCI chipset, that's shared with ThinkPad 560, so this driver should be named thinkpadx6x.cpp by following the model number logic.
