Hmm. The more I think about this, the more a sysv-style system seems

A system where the loading of option roms could be ordered by whoever builds
the rom image, if so desired, seems nice.

I'm not sure how that would play with the current order of loading things,
which is presumably done as pci ids are enumerated?

Or maybe we could just load whatever is in "early/" before the pci probing,
and "late/" after?
