Does it make sense to have the kernel use a swap partition?

You're not subtracting buffered and cached data.  Linux aggressively
buffers written data and caches read data for potential future use.
This data is easily evicted from ram (usually without requiring
anything to be written to more permanent storage), thus not negatively
affecting performance.

For various reasons, Linux's accounting of how much ram is in use
isn't quite accurate, but you'll get a much closer number by running
'free' in the terminal and looking at the "-/+ buffers/cache" line.
