I could reproduce the problem with both of following combinations:

   - Fedora 9's kexec-tools + Fedora 9's kernel
   - Fedora 9's kexec-tools + the latest ps3-linux.git + ps3_defconfig

Mac G5 w/ Fedora 9's kexec-tools works.

The same kexec-tools binary (i.e., Fedora 9's one) can boot the same 
kernel from kboot:

   kboot: chroot /mnt/root
   # mount /proc
   # mount /sys
   # kexec -l --initrd=/boot/initrd-2.6.25.9-76.fc9.ppc64.img \
         --append=root=/dev/ps3da1 /boot/vmlinuz-2.6.25.9-76.fc9.ppc64
   # kexec -e
