Surfing the archives, are we?
Any type of Ftr/Wiz combo (also including Pal/Sorc) can do fairly well in this fight because of Mirror Image - a fully buffed monk can avoid a fair number of hits as well. There's also a protection from poison spell around (available from Nym, iirc) which helps against the cloudkills. If you have a high Str tank to attack from behind your damage soak, that's even better.
The best place to set up the fight is on the narrow path leading to the exit. Four iron golems pounding away is too much, so you need to use the terrain to your advantage.
If you can summon earth elementals, they do good damage against golems. A zombie (lord?) has high resistance to bludgeoning damage and is immune to poison, so it also makes a good meatshield.
The real difficulty at this stage is the lack of +3 or better blunt weapons. Sometimes I go through the Underdark before doing this fight because you can buy what you need from the merchants if you haven't found anything.
