I get the following output:

# /sbin/fdisk -ul binary.img
You must set cylinders.
You can do this from the extra functions menu.

binary.img: 0 MB, 0 bytes
4 heads, 32 sectors/track, 0 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000b0e9b

     Device Boot      Start         End      Blocks   Id System
DKB_A1.img1   *        2048     1114111      556032   83 Linux
Partition 1 has different physical/logical endings:
     phys=(1023, 3, 32) logical=(8703, 3, 32)

but still doesn't work:

# mount -t vfat -o loop,offset=2048 binary.img /mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

The offset isn't always 512:

/sbin/fdisk -ul binary.img

Pay attention to sector size. Multiply start by sector size to get the
offset.
