Enabling /3GB and LARGEADDRESSAWARE might work, but I have found that because of certain video drivers (XP) would not work correctly with D3D or OpenGL apps (looks like some assumptions were made there that the space would be below 2GB). For one we could not get correctly our game and some of our tools to work on XP with /3GB (that was few years ago) Nowadays since we moved to Windows Vista/7 64-bit, we no longer have the problems (LARGEADDRESSAWARE) and our 32-bits sometimes go up to 3.5gb of usage.
