You could use reflection to fetch the value:

public static MvcHtmlString RadioButtonForEnum(
    this HtmlHelper htmlHelper,
    Expression> expression
)
{
    var metaData = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);

    var sb = new StringBuilder();
    var enumType = metaData.ModelType;
    foreach (var field in enumType.GetFields(BindingFlags.Static | BindingFlags.GetField | BindingFlags.Public))
    {
        var value = (int)field.GetValue(null);
        var name = Enum.GetName(enumType, value);
        var label = name;
        foreach (DisplayAttribute currAttr in field.GetCustomAttributes(typeof(DisplayAttribute), true))
        {
            label = currAttr.Name;
            break;
        }

        var id = string.Format(
            "{0}_{1}_{2}",
            htmlHelper.ViewData.TemplateInfo.HtmlFieldPrefix,
            metaData.PropertyName,
            name
        );
        var radio = htmlHelper.RadioButtonFor(expression, name, new { id = id }).ToHtmlString();
        sb.AppendFormat(
            "{1} {2}",
            id,
            HttpUtility.HtmlEncode(label),
            radio
        );
    }
    return MvcHtmlString.Create(sb.ToString());
}
