The serial number of your mac is also in the about box when you're in finder, use vo-m, select about this mac, move over to the scroll area containing the information, and it will report things like ram, hd, video card, and so on, as well as the mac's serial number. Of course, the apple care rep could have told you that instead of being so snide about it. On the other hand, (and I'm not defending the guy), they do get lots and lots of calls, and sometimes, they're being called by folks who know absolutely nothing about how to use a computer, and he likely was simply frustrated. Of course, this is no reason to treat a customer as you were treated, and you should email apple and let them know this happened, they generally try to offer a good experience to every caller, and if callers aren't happy with the experience, because the rep was rude or condescending (as in your case) then they really need to know that, they can't fix what they don't know about. But, with that said, there is a page on the apple site where you can check to see if your machine is registered.
https://selfsolve.apple.com/Agreements.do That will let you know about your apple care agreement, if you have one.However, the apple care is not the same thing as the registration your machine goes through when you first set it up. That simply sets up accounts and things, and if you want/have an dot mac account and things like that. It does get reported to apple, but it isn't quite the same thing as the apple care plans, it's simply a confirmation of ownership so to speak. I'm sure there's a way to get at this information, but I'm not sure where it might be located, so if you're really that concerned about it, you can probably get at it again by running the setup application, and skipping everything but the registration process (assuming that's possible, I've not tried it) Otherwise, I'd not worry about it, it won't affect the functionality of the mac itself, so if it's not critical for (say accounting purposes) I'd just not worry about it, if the os needs to know something, it will ask eventually.
