Package your driver entirely within I/O Kit and have I/O Kit load your driver by specifying a match on IOResources. If you search for "virtual" on the following web page, there's a detailed discussion of this. 2. Explicitly load your driver at boot time using a launchd daemon (or a startup item if you need to support pre-10.4). The following technote introduces these concepts and has links to more documentation. This email sent to site_archiver@lists.apple.com
