The list of invalid bitmap blocks (is that what they are? the header usually scrolls off the screen, so I can't see) printed at the end of an e2fsck run is too verbose. On vesafb, it took nearly a minute and a half to print the entire list from a dirty 9gb volume! I don't think it's important to list _all_ of the blocks if there are that many, and since there's no way to change VT's at boot or in a repair-filesystem shell, I'd suggest printing only an abbreviated list.
I want to keep with the decisions done by the ext2fsprogs maintainer. Other people might want to see that list.
