Just as with your laptop. Create a fake login.
So when someone beats you with a phone book or a tirewrench, you can say "the login is jdoe, password 123!" and they'll login and see your not so important files. When actually your login is janedoe password abc.
Same applies with encrypted partitions in your setup. Have a partition A at index N and a partition B at index M. A,N is the fake one, complete with files recently modified (.bashrc and cron will help with that). And B,M is your normal secure parition.
