Hi,

I've hacked a little bit on perl-Bootloader. So with change [1], I'm able to successfully install grub2 to my openSUSE 13.1 M2 Power7 LPAR. just change bootloader in /etc/sysconfig/bootloader to grub2, create /boot/grub2/{install_device,devce.map} and run update-bootloader --refresh

Haven't tried pmac yet. But it should do the trick as well there.

Have fun, Dinar
