I'm fairly sure that it would do, since as you mention above it just needs to know 
which partition is the OS X volume.

Out of curiosity does grub auto-detect blessed HFS/HFS+ volumes during installation 
and add them to the grub boot menu? If so, can you provide the grub.cfg. And do you 
have the output of fdisk and examples of grub.cfg entries that you have tried so far?
