Without knowing anything about the salting method, it will simply be a trial and error way of proceeding. If you 'knew' that the algorithm was md5($p.$s) and $s was a ascii string of 8 characters, then you have a better target (but a pretty large universe of candidates). If you know that it is md5($p.$s) and $s is 16 character lower case hex values, then again you can target that. If you find the salt is 32 bytes of random binary data, then you might as well give up finding the salt. I tested all binary data, from 1 to 4 bytes for md5($s.$p) and md5($p.$s) and the salt was not found.
