The flag that the application sets in the PE header is IMAGE_FILE_LARGE_ADDRESS_AWARE. According to Inside Windows NT, you can change this is a existing application but running imagecfg.exe from the support \directory in the Windows NT Advanced Server Edition CDrom or by compiling your application with /LARGEADDRESSAWARE. According to the book if you run the app on a normal Windows system then it should just run it in the 2 gig address space.
Yes, this is why I'm surprised that there would actually be an app that requires the 3G address space, and why it would be interesting to get a test case for that failure condition.
