I've tried one of the images, though it was an older one iirc. It's not necessarily necessary to port anything as there are already a large number of packages available to be built using the OpenEmbedded metadata and bitbake build system. See here: http://openembedded.org/

Depending on the libc version and soft-float type of the image, the standard familiar/OpenZaurus/etc. feeds may work with it too.
