When I added btrfs support to fedora there were alot of various utilities and such that needed to be changed in order to accomodate it, so the same sort of thing likely needs to be done with debian. There are patches for Grub1 since thats what Fedora uses, I suppose that there will be Grub2 patches in the future, but since the author of the grub patches uses fedora and we're on grub1 it's all we care about :).
