Just for the record, I have converted both my iBook G3 600MHz and my iBook G4
1.3GHz to grub2 and both are working very well (well, my iBook G3 seems to be
overheating once again, but when it works it is enough to test some programs).
I would recommend it for others to try it and go back only if you have annoying
problems. You problably won't, but who knows? :-)

As Michel already told you, this problem doesn't occur with grub2: it detects
the kernels that you have already installed (with no need to mess with update
yaboot.conf and run ybin), you can use tab-completion (very handy when you are
in some difficult situation) and all your filesystems can be ext2/3/4, xfs,
btrfs etc.
I just converted things here (in both notebooks) to ext4, as I want to take
advantage of delayed allocation and extents, so I don't know how it would work
with something outside of the ext-family.
I highly recommend it for other people.
And, of course, once you are satisfied with it, you can simply set it as default
in the NVRAM (say, with the boot-device variable of OF).
Hope this helps, Rogério Brito.
