Do you get any system error messages indicating that something is
running out of memory? If not, I'd say everything is OK with your system
- the swap is not used much because it simply isn't needed. The fact
that 56 kB of swap is used seems to indicate that your system knows very
well where it's swap is.

What do you mean by that? The swapctl output above shows that your swap
partition is being used. You can't force your system to use more swap by
issuing that command ;)

No, the swap partition is not supposed to show up in output of df.
I'm also running a 5.3-STABLE box with 256 MB of RAM and at the moment
the situation is like that:
premium# swapctl -l
Device: 1024-blocks Used:
/dev/ad0s1b 524288 0
I'm not worried at all :)
