From what I've read and experienced, you're not supposed to be able to run Boot Camp x64 on WhiteBooks. This statement is incorrect. I just thought I'd throw this information out there for people like me who were furious about not being able to run Vista/Windows 7 x64. All I had to do is go into my Boot Camp disk, and go to /Drivers/Apple and select the "BootCamp64" installer. After selecting this, the drivers installed with no issues. All functions of my MacBook work just as they did when I ran Vista x86. Hope this helps some people out.
