For info, I had this as well. Kernel 2.4.19 only. Using e2fsprogs 1.29.
I've not used tune2fs, just using -D switch to e2fsck. Using ext3 on all filesystems.
No obvious complaints from e2fsck, although I wasn't really watching it. No entries in /'s lost+found. No problems with other filesystems.
Only lost device files in /dev (about 120) with no discernible pattern.
