The first reply had it about right.  A 32 bit system can only address 4 GB.
When you have less than 4 GB memory, the system can map your BIOS and video
memory and other items to unused addresses.  When you have 4 GB, you see
that the result of this mapping means you can't use all your RAM.

You could try using a 64 bit version of Ubuntu, then you will see all your
RAM.
