Hail TaiDaishar,
Spoilers...
Oooooh, I remember this part. It was quite interesting. Only I don't remember all of the specifics :( If I can recall some of it, you have to go into a side room near the start of the entrance. A small sequence should happen with a lizzard lady. After that you have to talk to a head slave (would have to be in past I believe) he should be near the upper right of the cave. Then he gives you detailed information on how to beat the golems ( you have to be in the past and talk to the makers of the golems. Then choose what type of damage you want them to be vulnerable to). Hope this helps, though you probably found out how to do it already. Now that I think back, you do have to acquire some sort of magical item that lets you talk to the slaves. Forgot how to get it though... It's been way too long since I've played.
*edit* - Love those spolers.
