sadly no.  often, probling is not possible.  and assumptions about
memory sizes and layouts are typically not possible.

while you can view this as an advantage, i think this tilts toward
disavantage in little systems that have a ddr2/3 slot.  you can't
probe it, and you can't boot unless you have exactly the correct
memory module.
