Yes, that can go in separately. Also the load-dsdt patch for piix. And
run "make -C roms bios" once and "git add pc-bios/acpi-dsdt.aml".

Once all q35 bits are in seabios we should update the seabios submodule
in qemu, again run "make -C roms bios" and commit the bios update
(including the new q35-acpi-dsdt.aml file).
commit 01afdadc92e71e29700e64f3a5f42c1c543e3cf9 is a bios update if you
wanna have an example to look at.
Then the need to use '-L' goes away. That would be the final step once
all other q35 bits on both qemu + seabios are committed.

Kevin tends to wait for the qemu bits being committed before applying
the corresponding patches to seabios. So I think this would be the best
(1) piix dsdt load patches (the stuff discussed above).
(2) merge q35 series for qemu.
(3) merge q35 series for seabios.
(4) seabios update for qemu.
The q35 qemu series seems to be near ready for merge though,
so maybe it isn't worth splitting (1) + (2).
