A possible scenario is that the BIOS places the first 2GB where you'd expect, and then leaves a 2GB aperture for things like video card memory and DMA - placing your final 1GB above the 4GB memory address. This would result in only 2GB being visible to a 32-bit operating system, such as Ubuntu i386. Have you tried an Ubuntu amd64 Live CD? I assume that your system is capable of running a 64-bit version. Does this show the full range of memory? If so, I suggest checking your BIOS for such things as apertures and memory holes to see whether you can have your additional 1GB mapped to lower memory than it is currently being.
