No, sorry. You're still using BIOS emulation (which is an element of the "Boot Camp" that most people are referring to when they say the phrase) if you're running XP on a Mac. All you've accomplished with this convoluted method is to wipe out your OSX partition and replace it with a single XP partition. Avoiding use of the Boot Camp Assistant does not equate to not using Boot Camp.
Hope you've got a drivers CD.
Question for you, though...what's the screen with the lock and input box that you have a screenshot of during bootup? My first guess is that's its a dialog for an EFI password, and if it is, I'd be delighted to know how you set that up. Most tips refer to the Firmware Password Utility on the OSX Install Disc which, sadly, doesn't do what yours is displaying (at least in my tries).
