So this is what happens:
- after migration from old qemu to new old BIOS is used until reset
- after reset new BIOS is used
- after upgrade from old version of qemu upgrade does not have any
  effect until qemu is restarted

If this is a fair summary, the only issue with fixing BIOS bug
is migration from new qemu to old qemu, and we do not care much.
