Yes, we really need this for FreeBSD since that port uses the repository 
directly instead of FDT. Thanks for noticing this. We could adapt 
FreeBSD to use FDT (this is the only non-device-tree PowerPC port), but 
there hasn't been any reason to do that thus far given the availability 
of the repository information.
