The chrome registry does not expose a list of chrome packages, so no, 
there is currently no builtin way to do this. I'd accept a patch which 
hands back a list of the current set of chrome package mappings.

The resource registry is even more "interesting" because there are cases 
where resource mappings are looked up dynamically (from the directory 
service) and so we don't even know the list of resource mappings until 
somebody tries to load from them.
