Dear Stephen,

Is there a specific reason for not using get_ram_size()?
Since we know the exact RAM size, we may as well simply use it directly rather than "probing" for it.
You _think_ you know the size, but you can never be sure that all this RAM is actually present and working. There has been many discussions before why using get_ram_size() makes a lot of sense even in fixed size RAM configurations.
Right which is why the flow in this case is: 1) Read the place that "knows" 2) Pass that size to get_ram_size(), use returned value as what we really know the size to be.
