/proc/meminfo

[Brian Cluff]

I've never heard of RAM vendors using Mebibytes instead of Megabytes. 
It doesn't really make any sense.  Vendors use Mebibytes to make they 
storage sound like it's just a little bit bigger than the competition 
and ram sizes are still small enough that it would sound weird if 
someone were to advertise a laptop with weird decimal sizes on the ram.
