Not sure this can help me though. The order in which things happen is:

  1. smbios_entry_add() gets called for every "-smbios file=..." and
     "-smbios type=..." command line argument

        a. "type=..." is OK, we just remember the values for later

        b. "file=..." less so, because we have to load the blobs into
           *something*. In my v7 patch set I decided to load the blobs
           into *both* the legacy and new-fangled aggregate tables.

  2. smbios_set_defaults() is called

        - by now we *already* know the machine version we have, so
          we get to free the table we now know we won't need
          (aggregate if we're on <= v2.0, legacy if 2.1 or newer,
           see 1.b. above)

  3. smbios_get_table* functions are called and the various resulting
     blobs are inserted into fw_cfg.

  4. pc_guest_info_machine_done() gets called after all of the above.

        - placing a callback here is unlikely to be helpful, unless
          I'm missing something.


Please let me know what you think of the v7 patches:
