Hey Micro,
 Try booting to something else.  Matthew mentioned knoppix which would 
probably work as long as your LVM tools are included in your knoppix build.  
Basically, booting to something else (knoppix, memory stick, floppy disk, 
etc.) that has LVM tools *should* do what you need it to.  Your milage may 
vary.
