We have a patch that significantly speeds things up.
In the similar case 28+ years estimated for pass 0 turned into 208 hours total
operations after speedup patch was applied.
We plan to include it into reiserfsprogs 3.6.6-pre1, but if you need that urgently,
tell us.

This is not possible for reiserfs, I think.
reiserfs have non-constant metadata location , so while you can certainly
check fs consistency of some snapshot, you cannot fix it because all the real data
might have ben shifted to other blocks, old blocks might have been already freed and so on.
Bye,
Oleg
