Well the biggest culprit used to be the ethernet header code (a struct 
containing 6 octets that effectively assumed that sizeof would return 6).  
But that was fixed in February last year by the looks of things (by adding 
the "packed" attribute).  So maybe the hard work has already been done for 
the common cases: the only way to find out is to try it :-)
