Not sure how long these are going to be available, but right now you can download episodes of 24 for free from MySpace. It's being sponsored by Burger King, so I assume it's only for a limited time. Two episodes are available to download or stream, and they're good ones if you ask me:

• Day 1: 12:00AM to 1:00AM, the pilot episode.
• Day 5: 7:00AM to 8:00AM, the season five premiere.

Eventually, MySpace will begin to offer more episodes of 24 for the standard $1.99 per episode.

And on a semi-related note, your Jack Bauer fact of the day: "One time Jack Bauer went into a Burger King and ordered a Big Mac. And he got it."
