From your description this sounds like a kernel panic, which is virtually always caused by a hardware problem and nearly always the result of either (1) bad RAM or (2) something loose, like an Airport card. If you've added RAM, remove it. Running the Hardware Test CD that came with the Mac might help you isolate the problem.

Beyond that, since the 'book is new, I'd take advantage of your warranty and let Apple figure it out.
