You are a complete madman. You want to protect your data with a key stored on the most completely and utterly unreliable form of data storage still lamentably in use? Its not the 1970's anymore, get a real data storage medium! Get a usb flash drive, from there its a simple matter of changing the geli script to mount a specific usb device before starting. Look in /etc/rc.d/geli and geli2. I'd put your mounting and checks between the kldstat and the "if [ -z" in the geli_start() sub. You'll want to then use "geli -K" to input your key material, so you'll want to make sure your device is present, and that it has the expected key filename on it. You could also use dd and dump the first n sectors to stdout and pipe that into your geli command. Seems like quite a waste if you don't intend to use a passphrase.
