There is a 254 MB /boot partition, but when I access the LV, there seems to be 
one there as well.  Unless that is just the /boot partition mounted on /.

As I mentioned, the hardware is identical except for the replacement of one 
drive.  Can I just boot an LV-aware LiveCD and copy everything 
(except /boot, /proc, /tmp, etc.) to the new drive and just adjust the UUID 
of the new drive for the old drive in /etc/fstab?  I assume I can't overwrite 
a running system by booting the new drive and copying everything over to it.

The other alternative is to boot from grub on the new drive, but load the OS, 
etc. from the old drive? (somehow getting the LV to load during this boot.)

It is telling me that it is installing grub to the old drive with the LV, but 
when I boot it, I just get a black screen with "GRUB " on it (not a prompt, 
just the word) and no input accepted.  I can ctrl+alt+del, but can't type
