We shouldn't *need* an RSDP and RSDT/XSDT, though, since all they are
are pointers to the actual tables. Rather than hacking around it we
should probably just fix the fundamental problem.
That is what I described.
If something similar what I wrote gets implemented, you can simply
add ACPI tables to initrd as described here:
and if BIOS already provides them they get overridden, otherwise
they get added.
