Roughly speaking, vmstat only shows available mem *for processes*,
that is, mem that isn't reserved by the kernel for the buffer cache
and other usefull things. Also, currently we have some limitation to
address all physical mem, as can be seen on the mem lines in the
dmesg. The kernel only "sees" about 3G of your mem.
