Yup, but it's a bit of a pain. IIRC, you need to manually set up the loop
device, using losetup and its -o (offset) parameter. If you run 'sfdisk -d
/path/to/dd_file', the start parameter should give you the appropriate
offset.
Once you've set up the loop device, you should be able to just mount it in
the normal (i.e. non loopfs) way (mount -t ext2 -o ro /dev/loop0
/mnt/mountpoint).
HTH,
Alex.
