Password Generation Algorithm

I got this list of MAC, ssid and wpa passwords.
Its from zyxel modems used all over europe.
I know they use a algorithm to generate default ssid and password from the MAC adresse.
I just cant figure it out.
Anyway here is part of the list if anyone want to give it a try...

If they're halfway competant, they're using some sort of salt in the process. At which point it's probably cyptographically hard.

I suggest rubberhose crypto is your best approach.
