Thank you for your response.  But unfortunately that does not answer the 
question I asked.  I asked how to how to display the vertex labels with 
GraphPlot when the graph was created using a Combinatorica package 
function that directly creates a graph, e.g.:

    g = RotateVertices[Cycle[5], \[Pi]/10]; g = AddEdge[g, {2, 5}];
    g = SetGraphOptions[g, VertexLabel -> Characters["abcde"]];

So the structure of g is NOT the sort of structure you show.

Now I want to display those vertex labels with GraphPlot, but the 
"obvious" thing does NOT work:

   GraphPlot[g,Method->None,VertexRenderingFunction->(Text[#2,#1]&)

I want to reproduce with GraphPlot the sort of display I get with the 
Combinatorica function ShowGraph:

   ShowGraph[g]
