First, make the XP recovery discs just in case you ever need to go back.
Second, The easieast way to have a Vista recovery partition is to use the fectory Recovery discs. I think you can do your own Vista install, Install Rescue and Recovery along with the other drivers found here. Then Rescue and Recovery will make a recovery image for you.
If your Thinkpad has a Seagate Hard Drive you can use
Disk Wizard to make your own recovery discs. With the full version of Acronis you can make an "Acronis Secure Zone" which is a hidden partition you access with F11 at startup. It allows you to restore the computer from there.
