BTW, this bug is fixed now.

Sounds like bug #520846? Looks like that should also be fixed now.

Quite well, though there are still bugs that can prevent it from working
quite out of the box on PowerMacs. E.g. I still have to manually remove
search commands from /boot/grub/grub.cfg, or it fails to boot the Linux
kernel. However, even with problems like that, I like it much better
than yaboot because the boot time user interface is much more powerful.

AFAIK grub2 still can't boot Mac OS on PowerMacs, but you can always
boot it by holding the alt/option key during OF initialization.
In summary I'd say that it can be made to work by an experienced user,
but you should take it slowly and make sure you can go back to a known
working state at each step in case something goes wrong. In particular,
only change the boot-device variable in NVRAM after you've successfully
booted grub2 manually from an OF prompt.
