Hm, that sounds like it won't be possible to build one version of
SeaBIOS that works for *both* old and new qemu. That doesn't seem like a
great idea. I'd prefer something like:

- If Qemu provides the 'core' ACPI tables (i.e. not just SSDT) then 
  SeaBIOS uses them.
- Otherwise, it makes its own.
