So looking at SeaBIOS code, it seems to me we could simply make LKVM
lie to it by claiming to be coreboot and get away with it, no? We'd
basically avoid all the PCI allocation passes and such.
How difficult is it to initialize a struct cb_header data structure?
src/coreboot.c::find_cb_header() seems to be rather strict but
certainly nothing that we fundamentally can't do.
Another option is to extend the Xen codepaths to support LKVM too.
