How to get my Dell Ubuntu server to boot from a different drive?

I have an Ubuntu server. It's a Dell PowerEdge with a PERC 6 RAID controller. I'm trying to get it to boot to a different drive, and grub doesn't seem to be cooperating - it appears to attempt to boot to the correct volume and partition and then bonks out when mounting /proc - what gives?

Here's a photo of the screen when it dies
I'm using the UUIDs of each volume in my grub configuration, and the volume I want to boot from has separate /boot and root partitions. I've been hand-editing my various grub files: devices.map, menu.lst, etc., and have what appears to be the right UUIDs in the right places: the boot partition under "uuid", and the *root* partition on the kernel options. I've also got what I think are the right entries in the fstab, and I can get into the grub shell at boot time and poke around enough to confirm that my (hd0,0) is where I think it is and that the UUIDs all appear correct. I can provide all these actual files if it would be useful.
The existing and working boot drive is a RAID5 while the new one is a single physical volume that I'd like to use temporarily while shuffling around some other drives. Once I get this working, my plan is to do it a few more times in order to shuffle all the various files onto their intended disks.
