They might, but remember that Apple doesn't officially support Windows, just Boot Camp. I don't know how they would classify this problem -- as one with Boot Camp (which sets up the partition and the drivers -- and which, from your description, sounds like it worked as it was supposed to), or one with Windows itself. Of course, if you have AppleCare, it wouldn't hurt to ask them -- I'm just not sure if they would consider this fix to be under their mandate.
