What are the Crusaders on? "CrusadersofGreenmist"? If you want safe passage through Cabilis you'll somehow need to work them up to dubious as well.
I know with Crushbone it took me 3 nights of playing about 5-6 hours to get my troll SK from scowl to warmly with the Kelethin/Felwithe guards - and that was pulling the castle, the outside of the castle, including pawns and everything.
Faction is no easy thing, I'd grab a friend that can AOE...you pull every iksar marauder/manslayer/etc you can find (to ensure a faction hit), round everything up and AOE to death. Probably best done during the quieter hours so as not to offend the levelling lizards

That said it could be bugged, I'd treat the wiki as a guide rather than factual.
