good catch, we can add it, it will create /dev/mapper/loop0p1 node, I 
give a log for it's kpart usage in my testing,It's pretty easy for image 
partition
because you don't need to know offset for partition

root@intel_5500_server:/# kpartx -l sdb.img
loop0p1 : 0 20480 /dev/loop0 2048
loop0p2 : 0 10240 /dev/loop0 22528
loop deleted : /dev/loop0
root@intel_5500_server:/# kpartx -a sdb.img
root@intel_5500_server:/# ls /dev/mapper/
control  loop0p1  loop0p2
root@intel_5500_server:/# ls /dev/mapper/loop0p1
/dev/mapper/loop0p1
root@intel_5500_server:/# mkfs.ext3 /dev/mapper/loop0p1
.....

root@intel_5500_server:/# mount /dev/mapper/loop0p1 /mnt
root@intel_5500_server:/# ls /mnt
