The typical Linux way would be

1. Partition
2. Format a partition with mkswap
3. Edit the /etc/fstab file to indicate that the swap partition should be activated during boot
4. Then reboot (not necessary, but you want make sure everything still works )

However, the it seems like OS2008 ignores the /etc/fstab file. So, I'm not sure what the best way to automatically activate the swap partition is. Running a boottime script that calls "swapon" should work, but there may be an OS2008 equivalent to /etc/fstab, which would be a more elegant solution.
