 I see the patch in Linus's tree:

         commit 476a4813cfddf7cf159956cc0e2d3c830c1507e3
         Author: Laurent Vivier <Laurent.Vivier at bull.net>
         Date:   Wed Mar 26 12:11:53 2008 +0100

         loop: manage partitions in disk image


 and it works for me:

         # ./losetup -f -s /root/kzak/disk.img
         /dev/loop0

         # ls -la /dev/loop0*
         brw-r----- 1 root disk 7, 0 2008-08-21 11:34 /dev/loop0
         brw-r----- 1 root disk 7, 1 2008-08-21 11:56 /dev/loop0p1
         brw-r----- 1 root disk 7, 2 2008-08-21 11:56 /dev/loop0p2
         brw-r----- 1 root disk 7, 3 2008-08-21 11:56 /dev/loop0p3

         # mount /dev/loop0p1 /mnt

         # ls -la /mnt
         total 21
         drwxr-xr-x  3 root root  1024 2008-08-21 11:52 .
