Is that registered callback you're referring to? Or do you mean the
proto_reg_handoff function
I checked the K12 dissector and couldn't find anything different from
what I am doing.
The callback that doesn't seem to be called is passed in
prefs_register_protocol. The K12 dissector doesn't use that callback,
and so it must be using some other method to apply its changes.

I should clarify that the changes are "applied" to the data structures
in question (and the callbacks associated with each UAT are being
called). The problem is that Wireshark doesn't reprocess the packets as
it does when I change other properties.
I just tried it again (with the current SVN) and the packets are
reprocessed after applying the K12 preferences. Or, at least, packets
that were not previously dissected as anything (because the K12
preferences weren't set up right) are, after closing the preferences
window, dissected as what I want.
