EXT3?

How do I get ext3 to work in SuSE 7.3 kernel 2.4.16 upgrade? Is there RPMs out there that I need and do I do the rc.config change like reiserfs? I.e. initrd_module reiserfs,ext3. Currently I have an ext2 directory as SuSE 7.3 as default sets up ext2 instead of reiserfs or ext3.(After spending so much money to help develop reiserfs.) Any help would be appreciated. Thanks!
