Yes, it is fine to use ext3 on 2.2 for a filesystem created on 2.4. The only _slight_ possibility of confusion is whether the 0.0.7a ext3 has support for the reserved journal inode (#8), but I think that it does. IIRC, there were also a couple of bugs fixed since 0.0.7a was released, but there has not been a 0.0.7b release. You may want to consider getting the latest RH 2.2 kernel and at least extracting the ext3 patches out from there, because I believe they will include the fixes missing from 0.0.7a. Even so, I _think_ that the fixes made since 0.0.7a are relatively minor ones, but I haven't used a 2.2 kernel in a long time. That said, you don't necessarily _need_ to have ext3 support in your 2.2 kernel if you are only booting to it for a short time, as long as you shut your system down cleanly. That is one of the nice benefits of ext3 - you can mount it as ext2 easily. If you _are_ running 2.2.20 for a long time and want ext3, even then I believe that the 0.0.7a patches are still OK.
