If you're really into learning about the kernel I would pick up a book TBH. Something like this: 0470343435 (isbn).
Though there's certainly nothing wrong with looking at .01 to get an idea of how it all was born!
@elija: Thanks! ^_^
Just for Fun: The Story of an Accidental Revolutionary: Linus Torvalds, David Diamond: 9780066620732: Amazon.com: Books would be useful.
Best wishes ... cheers, drl
