Nope, it simply means even if I had 2GB RAM, there'd be plenty I'm not
using for anything but cache - I don't do much on this laptop but
browsing these days :)
What we are suffering from is explained neatly here:

Simply put, if the BIOS+chipset does not support mapping these reserved
areas to higher addresses this memory is lost to us.
My Dell Inspiron 9400 is about 3+ years old now. More recent hardware
have the necessary bits and pieces so that you can see all 4GB and use
it with 64 bit or 32 bit + PAE. Server chipsets had this kind of support
even earlier. Unfortunately for mine, Dell decided to only support 3GB.
