You need to remove the journal. You'll have to boot from a rescue CD of
some kind, and do something like:
1. Check to make sure the partition you're wanting to declare as ext2 is
not mounted. If it is, umount it.
2. # tune2fs -O ^has_journal /dev/hdX
(to remove the journal -- where /dev/hdX, is the device in question)
Repeat the above steps for as many partitions as you want to make ext3 ->
ext2.
3. # mount /dev/hdX -o rw /mnt
4. Edit /mnt/etc/fstab -- and change the fs-type to ext2 [1]
5. Reboot.
(That should just about cover it)

[1] This assumes that /dev/hdX is your "/" partition, of course. If it
isn't you'll have to mount your "/" partition and edit /etc/fstab before
you reboot.
