ext2 has this already: label's and UUID's. See man mke2fs, mount,
uuidgen and tune2fs:

[root at hibernia /proc]# uuidgen 
afb12621-42e3-4fc4-9b0c-dac73a1f7fb5
[root at hibernia /proc]# tune2fs -U \
afb12621-42e3-4fc4-9b0c-dac73a1f7fb5 /dev/Main_VG/test
tune2fs 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
[root at hibernia /proc]# mount \
UUID=afb12621-42e3-4fc4-9b0c-dac73a1f7fb5 /mnt/floppy/
[root at hibernia /proc]# tune2fs -L test /dev/Main_VG/test 
tune2fs 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
[root at hibernia /proc]# mount LABEL=test /mnt/floppy/

and you can then replace the device in /etc/fstab with either
LABEL=... or UUID=....

(this doesn't work for me on LVM devices.. but allegedly it does work
on regular partitions)
