I got it figured out. The problem was at the sata driver level. The instructions I found for rebuilding the initrd neglected to mention that I needed to edit modprobe.conf and add the appropriate driver information first.
I'm still not sure why it was able to get as far as loading the kernel before suddenly being unable to see the drives. If it needs sata drivers to see the disks, why doesn't it need them to read the boot partition? I didn't have to mess with grub or the boot sector after changing motherboards.
Grub uses the system bios to load the kernel and initrd. Then the kernel takes over and has to either have the needed disk/raid/lvm/filesystem drivers compiled in or available as modules in the initrd to be able continue and mount the drives.
