Add other os's to Opensuse grub

I just reinstalled opensuse 11.4 to fix some graphics problems and I installed opensuse’s mbr this time. It has detected my windows installs, but it hasn’t added my other operating systems such as ubuntu and fedora. How would I append these to the new grub?

Possibly the easiest way is to use this:
updategrub for openSUSE Legacy Grub (not update-grub!)

Or
