The bootloader or mkinitrd typically tells the kernel what the root disk is, so that's not a big deal. The boot disk, OTOH, is tough. Right now, we just assume the sysadmin knows what's he's doing, when he installs lilo or grub on a disk. You care about the boot disk when installing lilo... maybe there are similar situations too which I do not recall. As Alan said, besides EDD (only on newer boxes) there's really nothing.
