Well, nice tutorial, but this might be a little outdated. Mostly, especially for snow leopard(10.6.0), it is currently recommended to use a way of installing directly from the dvd. This might include using boot123, as already mentioned, or Empire EFI(what i recommend). Essentially with Empire EFI, you just put the empire efi disk in at boot, wait for it to load whatever it needs, and then insert the original mac snow leopard disk(the 29 $ disk, full, not upgrade - ofcourse you dont have to pay ;-) ) . Check out empire efi here :

Though if you are really looking to learn about hackintoshes, kexts and stuff, there is another advanced method. Though it requires that you already have a mac or hackintosh before hand. Using this, you can create a custom mac disk, that is custom suited to your pc configuration. This removes any problem of hardware not being supported, or if custom kexts are not available, at least you know whats not going to work on your hackintosh. This is probably the best method, but requires a mac, a little knowledge and patience. Give it a try, it really gives you a very good insight into hackintoshes and how they work.
