Unless I'm missing something, this is completely normal. You're using
78M of memory once buffers are factored out. Seems reasonable for a
just-started system.

For comparison, here's a moderately loaded machine running 2.2.19:

[doug@scooby doug]$ free -m
total used free shared buffers cached
Mem: 505 480 24 137 42 278
-/+ buffers/cache: 159 345
Swap: 101 0 101

Are you actually seeing performance problems or are you just worried
about the 'free' output?
