Ah, so romfile_loader is the "whole-blob" fw_cfg transfer method (so
far in smbios.c we've been dealing with individual fields, and
individual table types).

The only sticking point remaining would be who gets to generate the
Type 0 (BIOS Information) table and when, which is something QEMU
should arguably NOT be doing on behalf of SeaBIOS (or OVMF, or ...).

I guess everyone's busy with QEMU 2.0, so I'll keep playing with this
stuff on my own and bring it up again afterwards.

Obviously, more comments and feedback are welcome at any time, should
there be any interest :)
