When I used software raid (now I use hardware raid), I just installed
grub to the MBR of both drives. Since / was on /dev/mapper/mirror-root,
the kernel could always find the rootfs no matter which drive was
failed. This was with LVM over RAID1. I suppose without LVM's
automatic stuff, you'd want to use root=LABEL=root.
