I'm not sure if my method is the most elegant, but it does seem to work just fine. When you want to boot the other system, just take the Finder of the system you are currently running, and put it in a different folder so that it is separate from the System file. (I just keep a folder in the System Folder for this purpose. I call the folder 'New Finder' in the 7.0 System Folder, and I call it 'Old Finder' in the 6.0.X folder.) After you do this, the icon for the current System Folder will revert to a generic folder icon. You now should have no bootable systems on the drive. Then, take the Finder of the system that you want to switch to, and put it back in its appropriate System Folder with its System File. You will note as you do this that the icon denoting the "real" System Folder will move to the folder of the system that you wish to switch to. Then reboot. Voila, you are now running the other system. Note, however, that you will probably still have to rebuild the desktop file when you switch if you have done a lot of adding and deleting files, but that is true no matter how you switch systems. Also note that it DOES MATTER in what order you do the above operation. You need to disable the current system BEFORE you re-enable the other system. This will allow the current system to properly decide which System Folder is the one that it should boot. One caveat on this method: I have not tried it on a disk with multiple partitions, but it ought to work the same way.
