The default kernel isn't compiled with "highmem" so you won't ever see
above the ~900MB mark.  To get that install the smp kernel, which has
highmem enabled.  It will be something like
linux-image-<version>-<subarch>-smp. 

You should be able to type the following and get the kernel.

sudo apt-get install linux-image-`uname -r`-smp

Then reboot and make sure you select the smp kernel at the grub boot
prompt(it should be the default).  After that you should see all your
installed ram.
