GraphPlot bug? (missing self-loop)

How can I display self-loops using GraphPlot when the input is an adjacency matrix?

GraphPlot[{a -> a, a -> b}, DirectedEdges -> True] (* displays self-loop *)
GraphPlot[{{1, 1}, {0, 0}}, DirectedEdges -> True] (* missing self-loop *)

GraphPlot gives similarly surprising results when the input is a graph:

g = Graph[{a -> a, a -> b}, DirectedEdges -> True] (* displays self loop *)
GraphPlot[g, DirectedEdges -> True] (* missing self loop *)

Thanks,
Alan Isaac
