As I recall it Ghost will format the partition while restoring it. Check the manual to see if this still is true (it should be). This means you'll get back to your old FAT version if you ghost any of theese back.
Then you also can retrieve single files (or complete folders) using GhostExplorer. If you restore a file (etc) using GhostExplorer the file system of the target partition will be kept as is (of course, as everything else allready there also will remain).
You shouldn't restore a complete system partition using GhostExplorer as this would make XP confused - somewhere the system files "knows" what partition it is supposed to be at and I don't know what that happens if there is a mismatch.
I hope this helps at least somewhat - I'm not sure exactly what your goal is here.
