In the interim of moving ACPI tables out of seabios, developers should get the config from QEMU tree to keep things in sync.

The "seabios" word in the commands refers to whichever directory the seabios project has been cloned / checked out / extracted, doesn't it? For a second the cp command looked as if I should be able to find a seabios subdir (beside the roms subdir) in qemu. What about
- cp roms/config.seabios $SEABIOS_DIR/.config
- make -C $SEABIOS_DIR olddefconfig
(BTW, good to know! :))
