Drifting off-topic, but you shouldn't assume that.  Modern memory sticks
are in multiples of 8, yeah.  Crusoe processors take 12MB of RAM to
store microcode and cached instructions - the OS only sees, for example,
116MB.  Lower-end video cards share main memory, and I believe they also
just allocate themselves a chunk at boot and the OS never has a chance
at it.
