Public bug reported: After repartitioning my MBR formatted, multiboot HD GRUB would not boot my OSX partitions. My screen only shows "Error: Drive not found Error: file not found". I manages to boot into the partition with SuperGrub2disk and OSX Boot disks. By "try and error" I found out that there is something wrong in the OS-Prober script. The boot loader did try to look for a "sleepimage" file on the partition in the wrong place. the path in the prober-script was "/var/vm/sleepimage", but the file is located on the OSX partition in "private/var/vm/sleepimage" (OS X 10.6.8).
Changing the path in grub.cfg and under /etc/grub.d/30_os-prober to the above was my answer. At last, I don't know if the bug does rather affect GRUB2 than os-prober (with finds all my OS correctly), but I hope that someone can change this.
