I'm not familiar with those threads. But I've run 4e Dark Sun. We didn't need to change any rules. Though we did have psionic and primal PCs - these weren't a feature of our main campaign.
Good grief man! You pretty much skipped 2e DS as you were playing RM and made your D&D return when 4e came out and now you tell me you didn't change any rules? Just exactly what were you going to change them to, given that upthread you specified you were not very familiar with 2e DS?
