I currently have Vista 32 installed in Bootcamp and it works perfectly except that it won't show up in OS X under Startup Disk. This isn't that too big of a problem, I just shutdown, turn on, and hold option. I have a copy of Windows 7 and would like to start using it, but would like to confirm that using the upgrade function will work. Will it still be recognized when I press option? Has anyone done this? Also, does anyone know when 64 bit Win 7 will be supported in boot camp?
