Hm I wonder if I can test this. Can I just plug some arbitrary
VGA-capable graphics card into an empty PCI socket and
expect the console to come up?

Sounds like a pretty good idea, but since I ran into the
problem, what's actually happening in these systems on
boot? Are they reading/writing some arbitrary physical
location as if it was a virtual address?
