    You'd need that dissector to be registered by name (by calling
    register_dissector()) first.


Can you elaborate a bit? Who's 'that' ? my dissector or the PKCS#1? 
And how do I make the PKCS#1 register? It is one of the automatically 
created dissectors...

Sorry, I meant the PKCS#1 dissector (i.e., you'd have to modify the dissector).  Looking briefly at that 
dissector, I don't quite know how
register_dissector() should be called (in fact I'm not even clear what the entry point to that dissector is!).

I think that "pkcs" is normaly called from other dissectors using OID's. If you try to explain more explicity what you 
are trying to do possibly with an example trace we may be able to help you.
