I have some work-in-progress patches around these packages, that you
can re-use. Both packages build and have been quickly tested. However,
they need to be cleaned up, verified against toolchain dependencies,
etc...
Patches are attached, I'd be grateful if you could clean them up and
send them for review once you are happy with them.

Thanks
Gilles.
