The only reason that I can think of that would cause this is an initrd 
that doesn't contain the driver for the whatever adapter the disk is 
attached to.

Boot the rescue image and identify the adapter module.  When you've 
identified it, go back to the live system and make a new initrd using 
"--with <adapter_module>".  Don't replace the existing initrd, just 
create a new one in /boot.  If you then clone the disk, you should be 
able to boot the cloned disk to grub.  Edit the kernel definition and 
change the path to the initrd, selecting the one you've created for the 
new system.  It should boot properly, at which point you can replace the 
standard initrd path or fix grub's configuration file.

...and if you don't want to clone the system again, you can just boot 
the rescue environment, chroot to the sysimage, and make the initrd there.
