Yes that's annoying. Have a look at:
ftp://ftp.hq.nasa.gov/pub/ig/ccd/enhanced_loopback/

I get around the problem with this script:

#!/bin/sh
FILE=$1
PART=$2
DEST=$3

UNITS=`fdisk -lu $FILE 2>/dev/null | grep $FILE$PART | tr -s ' ' | cut 
-f2 -d' '`
OFFSET=`expr 512 '*' $UNITS`
mount -o loop,offset=$OFFSET $FILE $DEST
