If not, does anyone care to write one? I would do it myself...but I don't have time right now...maybe next week (unless someone beats me to it).

If you are bored and want to compile the vsdoc:
Here is the Firebug API.
Here is a blog post about the format for VS doc comments for intellisense.
Here is an example vsdoc (jquery-1.4.1-vsdoc.js).

I created the following because I kept typing cosnole instead of console. You can use it as a starting point (ish).

console = {
/// <summary>
///  1: The javascript console
/// </summary>
/// <returns type="Object" />
};

console.log = function (object) {
    /// <summary>
    ///  Write to the console's log
    /// </summary>
    /// <returns type="null" />
    /// <param name="object" type="Object">
    ///  Write the object to the console's log
    /// </param>
};
