It seems to work okay for me (Devil-Linux 1.6.0-RC3 32bit, server 
version, running from 2-partition USB, booting with Syslinux):

root@Samba:~ # cat /proc/partitions
major minor  #blocks  name

    3       64  156290904 hdb
...
    7        0     509118 loop0
    9        0  156290816 md0
  253        0     262144 dm-0
  253        1     573440 dm-1
  253        2     524288 dm-2
  253        3     131072 dm-3
  253        4  152043520 dm-4
root@dl1:~ # losetup -f
/dev/loop1
root@dl1:~ # losetup -a
/dev/loop0: [0801]:33 (/cd/bootcd.iso) read-only
