This is part of my series on running an unmodified Debian on the Joggler. See here for other posts on the same topic.
Just a quick update: you can now build and run an unmodified GRUB on the Joggler! A finished version of the patch I referred to in my previous post has been committed and is present in version 2.00~beta2, which you can get here. You still need to build it yourself, but it will work without any source modifications. Once the final release of 2.00 comes out, there should be a Debian package which will work :)
Thanks to Matthew Garrett and Vladimir Serbinenko for finalising and committing this patch.
