I've found this link- http://blogs.msdn.com/b/webdevtools/archive/2009/11/18/html-5-intellisense-and-validation-schema-for-visual-studio-2008-and-visual-web-developer.aspx to update the tags for HTML5, which isn't a whole lot of use when I'm using just one or two new tags. Is there any way to get Visual Studio 2008 to recognise the new Javascript related to these tags? That would be pretty useful.
