I would also suggest looking at the per-group dirty bit that Val Henson
developed, maybe 1.5 years ago.  This allowed e2fsck to limit its boot-time
scanning to only the small subset of groups/inodes that were modified shortly
before the crash.

I don't know how close to production-ready that code was, but it was at least
at the working prototype stage.  Some changes and updates are probably needed
(e.g. changing the per-group flag value to avoid conflicting with other
assigned flags) before using it on a newer kernel with ext4.
