After clearing the caches (/sbin/sysctl vm.drop_caches=3), one of my amd64 
console-only systems uses about 94MiB. With apache2 and samba running, 
dropping the cache brings it down to about 105MiB.

I've noticed that 64-bit Wheezy likes to cache a lot more in RAM. Without 
doing much on my 64-bit Wheezy XFCE desktop, it has built up to 2.8GiB used 
(1.1GiB cached, 740MiB buffers); dropping the cache reduces mem usage to about 
620MiB. This is a departure from 32-bit Squeeze with PAE and KDE which never 
used that much memory 'doing nothing', though it might be that 32-bit+PAE 
performs cache-usage computations sees only 4GiB RAM (32-bit) rather than all
