Maybe there should be something (I mean like, someone should come up with a standard :P) to trace switches in a path
A coworker of mine has written script to ask Rapid-STP speaking switches about their current topology and builds a graph again in gnuplot format.
A more challenging approach would be to scrape the mac forwarding tables and stitch things together. This would have to be done per-vlan. I think this approach (or similar) might be done by Openview's L2 featureset.
