In dmesg I see only this, but some problem with signanture is in syslog (at
the
end of this mail)

$ dmesg | grep swap
Starting kswapd
Adding Swap: 594364k swap-space (priority -1)

I just created a partition with fdisk /dev/hda6, done "mkswap /dev/hda6" put
the information to /etc/fstab and turned it on with "swapon -a". TOP shows
Swap: 594364K av, 0K used, 594364K free

syslog logs these kinds of kernel messages (those I guess are important):
