Hmmm, I tried that and was getting no results. Even less than what I sent you previously. So what I did, since mucking a few things up, was make a new debug kernel with matching vmcores and such. I think that the vmcore got off some how as I was getting rather weird messages when I tried various things when something didn't look right.
If I get any more panics and it looks like they are different I'll send them off to you.
Hope that helps.
