Do elaborate. Are you suggesting that I can load a 64bit kernel into my current setup and have access to all the RAM for the operating system? But if I were to run more than 3.2 GB worth of say Firefox it would let me go above that? Or are you saying just for each instance of that application? If so than since none of my applications will ever use all 4GB at once I'll just have more to spread around. Have I managed to confuse anyone else yet?
