Actually you should subtract the amount of data swapped from that
figure, which shows a huge difference.

Something in your system is using a huge amount of memory. It isn't
Squid (294MB) and it isn't the disk cache (176MB).

Look at your process listing one more time.

ps -lax | head -1 ; ps lax | sort -r -n +5 | head -10
is one way to look at it..

If you find no process using that missing memory then you have a kernel
problem.
