OK, this is the bug. You have a 0xee partition, that indicates that GPT 
should be used. But no GPT. Changing 0xee to 0x00 using fdisk, and 
making the partition bootable, helps with OVMF.

http://82.193.153.141/minimal-grub2-repacked-fdisked.iso

Produced with the command copy-pasted from your second email, and then 
fdisking the result:

$ xorriso -as mkisofs \
      -o minimal-grub2-repacked.iso \
      -r \
      --modification-date='2015121916023100' \
      -b /boot/grub/i386-pc/eltorito.img \
      --grub2-mbr minimal-grub2.mbr \
      -c '/boot.catalog' \
      -b '/boot/grub/i386-pc/eltorito.img' \
         -no-emul-boot -boot-load-size 4 -boot-info-table 
--grub2-boot-info \
      -eltorito-alt-boot \
      -e '/efi.img' \
        -no-emul-boot \
     -append_partition 2 0xef /mnt/iso/efi.img \
     -apm-block-size 2048 \
     -hfsplus \
     /mnt/iso

The result boots on DG965SS. Note: if I set the second partition as 
active, not the first one, then it won't boot. So much for the stupid 
BIOS :(
