I discovered on my workstation that there is a BIOS setting to cause the 
motherboard to remap everything above 3GB installed RAM up above the PCI 
address space. Without this option set, neither x86 PAE nor amd64 could 
make use of my last gigabyte. Probably has nothing to do with your 
hardware, but just a heads-up that these things do exist.
