This is an interesting issue in a geeky sort of way. Unfortunately, I don't have the time to investigate at the moment but I can provide a little more information in addition to what the OP posted.
Firstly, I can confirm that the issue does occur. I've reproduced this with IE6 on Windows XP SP2. In my case the main page is fine but if I click on the "Breaknecks" post, IE crashes. No need to scroll.
Secondly, this is not a WP issue.
Thirdly, whilst the page has a few validation errors, I do not believe that is the cause. There's none of the usual suspects and the html code doesn't turn up anything particularly suspicious.
I do, however, suspect that the issue is to do with the CSS. As many of us are aware, there are several obscure ways to crash IE via CSS. When this particular site is viewed without CSS , the problem doesn't occur.
I'd be interested to see what others find out.
