Actually, we've improved this in the BGL, so that the operator[] 
methods do work for adjacency lists and adjacency matrices when using 
bundled properties. Check out the new stuff in 1.32.0 :)

As for the other poster's question... I'll try to answer that later, 
but I think the problem is that bundled properties aren't support for 
the graph properties (e.g., the graph name), whereas they are supported 
for edges and vertices. This will probably change in a future revision.

This is a subgraph issue? We'll try to tackle this for 1.33.0; is the 
bug in the Sourceforge bug tracker?
