• If you don't have any idea how operating systems work, you should take the time to read a book about the basics. I recommend "Operating Systems: Design and Implementation" by Andrew S. Tanenbaum, but there are many others.
• If your eyes don't already hurt too much, you might want to have a look at "The Design and Implementation of the 4.4BSD Operating System" by Kirk Mckusick.
• A good way to start hacking is to learn how to write modules. The deadly.org online-magazine has an interesting article about this topic: http://deadly.org/article.php3?sid=20010812210650
• We've got man(1) pages for almost everything in the kernel (section 9). apropos(1) and grep(1) are your friends, too. So when you're reading some pieces of code that you don't understand, you should use these commands extensively.
• Read the list's archive. Your question is being posed (and answered) every few month.
• Read NetBSD's Kernel Programming FAQ, take a look at FreeBSD's Developer Handbook.

BTW: It is NOT a good idea(tm) to post the same message to both, misc and tech.

PS: Is there a FAQ for the "tech" list?
