Heat margarine and chocolate chips in the top pan of a double boiler over low heat, stirring occasionally, until melted and smooth. Cool slightly.
Put marshmallows and nuts in a large bowl; stir in chocolate.
Tear five 9-inch sheets of waxed paper and sprinkle each generously with coconut. Divide dough into fifths and place each fifth on a sheet of waxed paper. Roll tightly into 2-inch diameter logs and refrigerate overnight.
Before serving, unwrap from waxed paper and cut into 1/2" slices
