Google definitely does do an algorithmic rendering of your page these days. How else would they measure "above the fold"? Or give more weight to links in the content area compared to the footer or side panel?

Actually, Microsoft was the first to file a patent on algorithmic rendering of web pages. So Bing may be in the same situation as Google here.
