So I assume it is impossible in Mathematica 6.  Though the following code, taken from the Guidebook, works wonders in 5.2:

DashHiddenEdges[g_Graphics3D, dd_, opts___] :=
Module[{gr3d, gr1, gr2},
 (* do not display graphics *)
 gr3d = Append[g, DisplayFunction -> Identity];
 (* the dashed polygon edges *)
 gr1 = Graphics[gr3d /. Polygon[l_] :> {Dashing[dd], 
                           Line[Append[l, First[l]]]}];   
 (* the original graphics *)
 gr2 = Graphics[gr3d];                  
 Show[{gr2, gr1}, opts, AspectRatio -> Automatic]]

So it is then safe to assume that Mathematica 6 is incapable of doing even simple things possible in 5.2
