I also have 4 gb of RAM (new Quadcore Intel) and 'free -g' reports '3'
as well, I suspect this is underrounding to the extreme, and 'free
-gb' returns a more realistic number:
fox@newbox:~$ free -gb
total used free shared buffers cached
Mem: 4018106368 3988586496 29519872 0 26746880 2479407104

Swap: 8389775360 5529600 8384245760
It isn't that RAM has a FAT - those things only are present on
filesystems. It is more likely that free's interpretation doesn't
include kernel memory. Also, 4gb may be 4*1024*1024 not 4*1000*1000,
although that is more likely to be a concern with hard disk capacity.
