[SOLVED]
I'm still not sure what the "right" way to do this is, but the following
solved my specific problems:
OperationRegistry registry =
JAI.getDefaultInstance().getOperationRegistry();
new ImageReadWriteSpi().updateRegistry(registry);
That code covers the operation in
/META-INF/services/javax.media.jai.OperationRegistrySpi, but not the three
in /META-INF/registryFile.jai. Probably these would have to be handled as
well when loaded some other specialized image types, but they weren't
required for GTopo30 files.
Thanks for the help, Michael!
