I'm sorry I didn't respond sooner.  I guess I don't know from looking at 
fdisk code, but I've done a lot of partition manipulation with it, and 
I've never experienced it touching anything except for the partition 
table for the primary partitions.  Extended partitions are different, I 
think we discovered a while back on this list that extended partitions 
are a "linked list" so it may not work the same.

Hope everything works!
