yeah, i guess so. Right now i only ran into the build failure so there's
hope :) Here's a config that fails to build for sure:

note, on 32-bit there's a yet unfixed initrd corruption bug i've
bisected back to:

| x86: introduce init_memory_mapping for 32bit

so if you see something like that it's probably not a bug introduced by
your changes. (and maybe you'll see why the above commit is buggy, i
havent figured it out yet)
