The Dorian glitch does still work. Look in The Oblivion FAQ sticky and do a Ctrl+F for Dorian. I wrote a detailed explanation there of how to get as much money as fast as possible.
One thing was recently brought to my attention though. Instead of punching Dorian to reduce his disposition you can just cast command humanoid on him for 1 second and it will reduce his disposition to 0. You'll know what I mean when you read the explanation.
