How about converting to a largely device-name-independent setup based
on UUIDs or labels? You can find a file system's UUID by running
blkid -s UUID -o value /dev/xxx
and then replace the literal device name with UUID=.... (Some
kernel/udev combinations also support /dev/disk/by-uuid/... device
paths, but Athena's does not appear to, so that won't help with GRUB;
however, I believe it should be more robust in the face of such BIOS
setting changes anyway.)
