I think I've come up with a reasonably good solution.  I've attached 
the patch to packet-eth.c.

Basically, I've added (optional) support for heuristic sub-dissectors 
within dissect_ether_common.  The default is for this to be inactive, 
but it will allow others to interpose their own dissectors in the 
future without having to edit packet-eth.c.

Incidentally, I think the ISL glue in packet-eth.c could be moved out 
to an heuristic sub-dissector once this patch is in place (although 
you might then want to turn on the heuristic sub-dissectors by 
default).
