This should not be necessary. The on-disk structure of an ext3 file system
is the same as for an ext2 file system. The only difference is the addition
of a journaling file + journaling mechanism. So an ext3 filesystem should
mount fine on a system that only knows about ext2. You just don't get the
benefit of the journaling.

None of that should be needed. What sort of error messages did you get?
Why don't you try booting from a rescue disk (e.g. the one Dave Dittrich
posted about recently) and running e2fsck on your system disk.
