Probably makes more sense to move to qemu, then pass the tables to
seabios as qemu knows which virtual hardware is requested by the user
and thus is present and which isn't.

Having a brief look at the coreboot code it seems static stuff (compiled
by iasl) and dynamic bits are combined into the final dsdt table, is
that correct?
