You could either mount the second disk on the first machine, as I talked 
about earlier, or use dump with ssh pipes.

Boot the new machine with a boot CD like knoppix, all it needs is the 
ext3 restore and ssh and something to create the LVM volume.

Then run something like this (As root):

(create /dev/New/Root with lvm tools)
...
mount /dev/New/Root /mnt/newroot
cd /mnt/newroot
ssh root at oldmachine "/sbin/dump 0f - /" | /sbin/restore rf -

if you can't ssh in as root, then do something like this:

ssh you at oldmachine "sudo /sbin/dumo 0f - /" | /sbin/restore rf -

Or, if you don't like using ssh pipes, just use rsync.  It won't 
preserve atime and other extended attributes like dump/restore.
