Yes, we are absolutely planning to add such scaffolding support to ASP.NET MVC. In fact, you can preview it if you download the MVCToolkit from here. It contains an MVC blog project that includes this. It's very preliminary, but can give you a sense of where we're going.
I don't quite understand your second question. Currently, we only support Linq to Sql, but will soon support Linq to Entities as well (though it's probably not what you're asking!).
