Yes, there are many ways to chainload a second GRUB. As fs_embed is already 
implemented for btrfs I thought it would be good to be available for ext2 as 
well. So question is, if this should be done (I am willing to do so) or if 
grub-devel is not interested in this. This is why I ask first, before doing the 
work. :-)

Thanks. :-)
