4GB is *not* available to your system. You have a 4GB address space,
but some of that must be used to access BIOS, video RAM, etc. What's
left over is used to access RAM. See

That said, I'd expect you to see more than 2GB. Do you have multiple
fancy video cards, or something else that might include lots of
onboard RAM?
