"SeaBIOS already has an ATA driver" doesn't seem a convincing argument for
making IDE special, because I expect the BIOS will grow support for other
block devices.

Either expose ever block device qemu knows about, or have extboot as a regular
block device with no special handling. I strongly prefer the latter option.
In fact I'd much prefer to see extboot rewritten to just virtio-block.
Simple virtio clients really aren't that hard to write.
