The world is nipping at M. Yeo's heels.  Someone else has just tested 
Boot Manager against a disc with the LVM metadata on it, and we've done 
the tweaking to locate the partition names properly.  (Although coded 
blind, there wasn't much to do, apart from fix a wrongly sized field 
declaration in a data structure.)  I've been sent a screenshot of Boot 
Manager correctly displaying the LVM partition names.  There were no 
FE01 problems, so thus far M. Yeo is still alone in that particular 
boat.  (-:
