Note: just using (test register) as export-list is fine, since
you are exporting register, anyway. You only need that if register
shouldn't be exported.

Your .setup file installs embedded-test as `syntax' (see property-list
in the invocation if `install-extension'), which means the extension
has no runtime part (and thus nothing is loaded at runtime to
provide the necessary runtime code). Remove the `(syntax)' and it
works.
