Please be aware that this is cross-posted to both the SeaBIOS and coreboot
mailing lists.  I know this is generally frowned upon, but I believe the
subject is valid for discussion in both forums.
I have a coreboot/SeaBIOS image containing an option ROM that works for
multiple graphics devices (seven or eight of them).  These graphics devices
come from the same vendor but each device has its own (unique) PCI Device
ID.  If I'm going to load the driver from SeaBIOS, I need to have a copy of
the option ROM file, each with the name of the target PCI device (e.g.
"pci1234,5678.rom").  Having seven or eight copies in the BIOS image file is
a waste of space.
For the SeaBIOS case, is there any reason you can't simply place the
rom in a cbfs file "vgaroms/myrom.rom"?
