I must admit i never look at the beginning and end of a partition, Fdisk is 
pretty flakey, i have seen it change the geometry of a disk before, even 
effecting its reported size in the bios.

Did you create the partitions initially in fdisk, or in the FBSD install 
proccess?, that might explain something.

But no doubt, you can create another partition with the remaining space, the 
biggest worry i used to have was formatting the wrong drive :)
