Layered Pumpkin Torte

In a medium bowl combine graham cracker crumbs, melted butter, and 1/4 cup sugar. Remove 1/4 cup crumb mixture; stir in chopped pecans; set aside. Press remaining crumb mixture onto bottom of an ungreased 13 x 9 x 2-inch baking pan. In a small mixing bowl combine cream cheese, 3/4 cup sugar, and 2 eggs. Beat until well-mixed. Pour over crumb mixture in pan. Bake at 350°F (175°C) for 18 to 20 minutes. Cool on wire rack. In a medium saucepan combine 1/3 cup sugar and gelatin. Stir in 2 egg yolks, milk, cinnamon, and salt. Cook and stir over medium heat until bubbly; stir in pumpkin. Transfer mixture to a large mixing bowl; cool. In a small mixing bowl beat egg whites until soft peaks form. Gradually add 1/4 cup sugar; beat until stiff peaks form. Gently fold egg whites into cooled pumpkin mixture. Spoon over cooled crust in baking pan. Cover; chill at least 4 hours or until pumpkin mixture is firm. Just before serving, sprinkle reserved crumb mixture on top.
