If you're using the x86 (32 bit) version of Ubuntu, then it won't see the entire 6 gigs. A 32 bit OS can only address ~4 gigs of RAM. You need the 64 bit version of Ubuntu (AMD64).
You can:
1) Switch to using (K)Ubuntu 64-bit
or
2) Enable PAE extensions in your kernel (will require a kernel recompile). Physical Address Extensions allow a 32-bit operating system to access more than 3.2Gb RAM; this is a limitation to all 32-bit OS's, not just linux. Enabling PAE allows access to upto 64Gb (?) RAM.

Make your own: Ubuntu, Kubuntu, Xubuntu, Mythbuntu All-in-One Live DVD
"I never make mistakes; I thought I did, once.. but I was wrong."
You can also install the 'server' version of the kernel via the package manager (it has PAE enabled by default).
