Okay, now we're getting somewhere.

First off, you did chroot, correct?

Secondly, how was /dev/mapper/vg0-sysroot setup on the old
system?

Is the rescue mode creating a /dev/mapper/(whatever)?

In a nutshell, GRUB must understand how to load the root at
boot.  It would really help if you'd post your old _and_ new
/boot/grub/grub.conf and /boot/grub/device.map files as well
as _detail_ your _exact_ disk arrangements.

You used the correct procedure AFAICT, but you're having some
boot-time issues in mapping the BIOS fixed disk to the Linux
device.
