I have no clue about the technical feasibility. You'll probably only know if you try it :) Regarding licensing, IIRC Michael ported the ACPI code by: - posting the qemu patch on both qemu-devel and the seabios list, - CC'd all people who ever modified the seabios files being ported (this is easy with "git log") - asked all CC'd people to respond with an Acked-by if they agreed to relicense their seabios contribs.
