I've stickied Bingdude a term which results in a sitelink entry for the top result. It has appeared like that for several months now.
ken_b - if you type in your domain name into Google you will most likely see your site appears top of the SERPS. It has an enhanced entry with, as you say, two columns of additional links to the main pages in your site. Yes, that's the type of Bing SERPS entry we are discussing.
