I reached the same conclusion you do.   Actually, I got your reply just as
I was about to delve into all the nice output of I82596_DEBUG 10 :)

Unfortunately, your modified driver doesn't seem to help... still crashes
at the same point :(

I'm going to investigate this further.  I'll let you know what turns up.
