I just noticed from man 8 bsdlabel:

COMPATIBILITY
     Due to the use of an u_int32_t to store the number of sectors, BSD labels
     are restricted to a maximum of 2^32-1 sectors.  This usually means 2TB of
     disk space.  Larger disks should be partitioned using another method such
     as gpt(8).

I suspect this applies to amd64.  man 8 fdisk makes no
mention of data size problems, but I would suspect it as
well.
