Yes.  The i440fx acpi tables are compiled in and will be used as
fallback in case qemu doesn't provide acpi tables.

Yes.  Old seabios will simply ignore the qemu-provides tables and use
the compiled-in ones.  That is limited to the 'pc' machine type though,
q35 will not work this way.  q35 needs other tables and this was the
reason to let qemu provide the tables in the first place.
