It is in Preferences/General/Startup and shutdown. For me, this appears in the list:

Usage data gathering plugin
Usage data recording plugin
Equinox Provisioning Platform Automatic Update Support
Mylyn Tasks UI
Mylyn Team UI
Eclipse UI
Automatic Updates Scheduler

Also, I tried installing the plugin on linux (Ubuntu 10.10), and it simply said: "Cannot complete the install because one or more required items could not be found." Are there prerequisites for the plugins? Maybe linux prerequisites would also apply to Mac OS X?
