If you stopped here and used SeaBIOS, it would solve multiple issues at
once.  SeaBIOS is the Bochs BIOS converted to C, understands VGA ROMs in
CBFS, and can have multiple payloads (I saw that in the other thread.)

Now might be the right time for you to try it.

Yes, I've seen quite a bit of traffic on SeaBIOS, and it does look like
it might answer a number of questions at once.

Looks like it's worth a go.
