Richard,
Thanks for listing the steps, I think this is the clearest "how to" I have seen for this, as I had attempted to follow this guide: http://www.hdrsoft.com/resources/dri.html#capture and got caught up trying to have the exposure bracketing do the trick- well and I had a hard time understanding a few of the steps they were listing - as a newbie I sure as hell wont understand "...take as a basis the exposure time measured for the highlights. Multiply this number by 4 to find the next exposure with a stop spacing of 2 EV..."  so I pretty much tuned that part out...  

Needless to say, I like your explination a hell of a lot better!!
I have got to try this very very soon!
