Ok. Suggestion for how to handle this (not yet tried). Change the assumption about the end marker. Right now the end marker only uses the first fields and the user data happens to always be zero. If we change the pci matching code to interpret end markers with a non zero userdata as a pointer to the next table it all seems to come out in the wash, although there are some tricky details to consider - who frees up the extra tables on a module unload (if anyone), and how do we manage multiple modules with chains of tables (or do we just disallow that case).
I think it also means we need to be able to go pci table -> owner ?
