This mode keeps a file around the same size as your memory, and mirrors the contents of said memory. I've used these options in 10.4, 10.5 and 10.6.2: pmset -a hibernatemode 0 nvram "use-nvramrc?"=false <reboot> rm /var/vm/swapimage After another test reboot the swapimage file should not reappear. You can now shrink your partition with 'diskutil resizeVolume'.
