I have no filesystem experience and almost no experience with kernel code in general, so I would not be anyone's first choice for a task like this. However, since it mainly appears to be an integration exercise (using the code from GRUB and making it work in linux), it might well be doable for me. As a bonus, being highly inexperienced, I have no expectations of doing anything correctly, and thus would not react badly to lots of criticism. So to summarize - if anyone else would like to undertake this work, they probably should. But if no one has the time/will, then I would be happy to give it a try.
