'sudo fdisk -l /dev/hda'; among other things, you should see a line a
bit like this:

/dev/hda13              Apple_HFS Mac OS X            10554321 @ 91845680  (  5.0G)  HFS

Take the device name from the start (in my case, /dev/hda13) and put it
in a macosx= line at the bottom of /etc/yaboot.conf. Your yaboot.conf
would therefore end like this:

image=/boot/vmlinux.old
      label=old
      read-only
      initrd=/boot/initrd.img.old
      append="quiet splash"

macosx=/dev/hda13

Now run 'sudo ybin -v' and reboot.

Cheers,
