I would think that you could also just look at the graph for you uplink
port(s) or etherchannel and the should represent the combined bandwidth.

At the risk of seeming to ask a silly question, why?
Most switches today have loss-less fabrics, meaning you can run all
interfaces at line rate and not saturate the backplane. So.. what value
is there to monitoring a number that is irrelevant?
That said, use rrdtool as the backend, routers2.cgi as the front end,
and create a summary graph of all the interfaces on the switch.
