Just look up the chipset - pre-Santa Rosa Intel notebook chipsets didn't
handle remapping the I/O space above 4GB, so even with a 64-bit CPU and a
64-bit OS, I/O space would consume the top of RAM below 4GB.  Whether you
decide to put 4GB or 3GB or 2GB of physical RAM in the system is up to you,
but if it's DDR2, 2GB SO-DIMMs are not a lot of money.
