Okay, solved my own problem.  My backup of root "/" that I restored onto the 
new logical volume /dev/Volume00/TempVol was lacking the block device to access 
TempVol.  A simple:

# mknod /dev/Volume00/TempVol b 58 4

was all I needed and up she came.  I have a vague recollection that one of the 
manpages for an lvm utility mentioned something about backup/restore of special 
files but I can't remember which one...
