ext3 is not compatible with itself

Until now, it has generally been possible to mount ext3 filesystems on older kernels - even those which only support ext2 (with one ugly exception involving a distributor which was heavily pushing SELinux features).
The exception affects most ext3 filesystems that were first created before sometime in 2004, and it makes ext3 incompatible with itself. I was angry when it tripped me; the "bugfix" should have created a new filesystem type right then.
