It looks to me like this may have been broken by revno 1945 on debian-cd, which dropped the population of $CDDIR/boot/grub/efi.img. Mathieu also mentions that hybrid boot would require the options -eltorito-alt-boot -e boot/grub/efi.img -no-emul-boot -isohybrid-gpt-basdat. Dann, is this something you can drive resolution of?
