format = md5_gen(0)   type =  md5($p)   (raw-md5)
format = md5_gen(1)   type =  md5($p.$s)        (joomla)
format = md5_gen(2)   type =  md5(md5($p))      (e107)
format = md5_gen(3)   type =  md5(md5(md5($p)))
format = md5_gen(4)   type =  md5($s.$p)        (OSC)
format = md5_gen(5)   type =  md5($s.$p.$s)
format = md5_gen(6)   type =  md5(md5($p).$s)
format = md5_gen(7)   type =  md5(md5($p).$s)   (vBulletin)
format = md5_gen(8)   type =  md5(md5($s).$p)
format = md5_gen(9)   type =  md5($s.md5($p))
format = md5_gen(10)  type =  md5($s.md5($s.$p))
format = md5_gen(11)  type =  md5($s.md5($p.$s))
format = md5_gen(12)  type =  md5(md5($s).md5($p))      (IPB)
format = md5_gen(13)  type =  md5(md5($p).md5($s))
format = md5_gen(14)  type =  md5($s.md5($p).$s)
format = md5_gen(15)  type =  md5($u.md5($p).$s)
format = md5_gen(16)  type =  md5(md5(md5($p).$s).$s2)
format = md5_gen(17)  type =  phpass ($P$ or $H$)

md5_gen(7) is md5(md5($p).$s) with a fixed 3-byte salt, if I remember  
correctly (Jim?).
For any other md5(md5($p).$s) hash, you should use md5_gen(6).

IPB2 uses md5(md5($s).md5($p))), so you'd want to use md5_gen(12).

Same procedure as before:
user[tab]md5_gen(12)HASH$salt

* TAB is field separator
* $ is salt separator
* md5_gen(12) is hash type identifier
