How does using LVM expose anything more than using normal /dev/[sh]d?
devices? As far as I get the vserver concept (I'm at the theoretical
stage, because I lack a RedHat system, and compiling this stuff is
nontrivial on SuSE. Haven't tried yet on Debian), the vserver admin does
not handle it's server on a /dev/ basis, as the vserver gets an already
completely mounted filesystem setup, ...
So this does not make sense to me? How does putting the vservers into
LVM devices expose the raw data to a vserver root?

Nope, it does not seem reasonable. Only drawback of using LVM for
vservers is, that you cannot unify the servers, ...
OTOH, you get a per vserver quota, that you can change while the server
is online. With hotpluggable discs (scsi, firewire, usb2.0 come to mind)
you can even add storage space online, ...
