I'm using pylab=inline mode to display the plots on the webpage. However, because of the way the notebook infrastructure is currently set up, whenever the server sends a figure(message type display_data) the content is fit into a container by creating a new  <div> which is appended to a cell.

I would dig around IPython/zmq/displayhook.py and  zmq/pylab/backend_inline.py

I think you might want to create a wrapper around fig that have a _repr_html_ in which you build the html/base64encoded figure yourself.
You will then be able to put any information you want into the div's . 

You can also have a look at IPython/docs/example/notebooks/display_protocol.ipynb

That shows example of such objects and how to bind display_hooks for other objects.
