It seems to me that this exactly the other way around. The patch is 
probably already in -mm and is doing what it is supposed to do: don't 
report partitions whose system ID == 0.

Can you try to give the empty partition a type different than zero? You 
don't need to make a file system on it or anything, just change the type.

Or check if the patch Randy is pointing to is already in your tree and 
revert it.

I think this is a good argument not to include this patch on the -stable 
release...
