Using attached image-mount script that is possible. Like this:

  ln -s image-mount image-losetup
  fdisk filename
       (remember to set correct cyl/head/sect before creating partitions)
  ./image-losetup /dev/loop7 filename 2
  mkfs.ext2 /dev/loop7
  mount /dev/loop7 -t ext2 /mnt/somewhere
  umount /mnt/somewhere
  losetup -d /dev/loop7

or

  ./image-mount filename 2 /mnt/somewhere
  umount /mnt/somewhere

Good news is that image-mount and image-losetup scripts get both size and
offset of the partition right, so mkfs creates correct size file system. Bad
news is that it only works with losetup and mount programs from loop-AES
package. Google for "loop-AES" if you can't find it.
