I like this. Puppy Linux is great for older computers since its so lightweight. Only think I could find that would run on this old HP laptop. Can you include some additional independent address generators? Perhaps brainwallet.org and the Cascascius tool? If I'm going to send a significant amount of BTC to cold storage I'd like to be able to verify the keypairs or passphrase>addresses with more than one tool, ideally at least 3.  This will be handy for people who can also not afford the latest-greatest tech.
