Of course your empty partition could also simply be an empty ext2 
partition if Grub installs on that okay.

I don't know how big the smallest ext2 must be but I don't think very 
big and no 1GB btrfs partition or anything of the kind.

Then using "my" patch you could even have a PV header on it and nothing 
else and Grub would install on that also, I believe, although I haven't 
tested on partitions, but that is nonsense if you can just use a ext2 
partition right.

The PV header is also just one sector. But at this point because you 
need a custom grub I would consider that a bit nonsensical if you can 
just put ext2 on it?
