Doesn't grub need to know the bios disk id for subsequent stages of the boot and where to find the root filesystem? I think it matters whether or not bios remaps your 2nd drive to the first id.
GRUB boots first partition on a given disk, and then kernel boots file systems from RAID's. Once /boot RAID is mounted, any changes are written to all disks.
What is the hd number you give in the setup command? And what if bios doesn't call the remaining live disk that number after a failure?
