It is a little more complicated... i386 also supports >4GB with the PAE 
kernel option... it is frequently better to use this then to use amd64 
because (a decreasing I hope) number of ports do not compile and/or work 
properly on amd64... for example if your using the machine as a GUI 
desktop *AND* you have a nvidia video card you get almost 10 times 
better performence with i386 because amd64 has a hard time reconizing 
PCI cards installed "above" the 4gb limit (the phsycial addr is above RAM)
