Yeah, good point, so we need to figure out something for 0.12.0.
Sebastian's suggestion of loading roms from 0xc0000 first and then from
PCI devices is a good one, but I think the problem with that is that the
roms don't necessarily have to be contiguous in that space. For
instance, the lower bios portions are technically in the rom area which
leaves a big gap in the middle.
We could just assume that knowledge in SeaBIOS.
We'll also need the ability to select whether to use PCI or legacy rom
loading for each PCI device (via a qdev property). This will need to be
plumbed into the machine compat bits such that -M pc-0.11.0 uses legacy
rom loading. Otherwise, the PCI devices will be detectably different
within the guest.
