ASP.NET Dynamic Data and other ORMs

Searching to see if I could use with the ASP.NET Dynamic Data some other ORMs besides the EF and LINQ to SQL, I stepped on ValidDataContextType method from the System.Web.DynamicData.ModelProviders.SchemaCreator. The method body looks like this and I think it provides enough information about the extending to other ORMs:

public virtual bool ValidDataContextType(Type contextType){
       if (!IsDataContext(contextType)){
              return IsObjectContext(contextType);
       }
       return true;
}

The only valid DataContexts are System.Data.Linq.DataContext or System.Data.Objects.ObjectContext. So if you want to extend the ASP.NET Dynameic Data you can do this by implementing a LINQ2 or EF provider to some database. Here, Frans Bouma gives more references aboute this issue.
