I updated the fsck_lfs sources to latest -current except for this patch:
---------------------
PatchSet 86 
Date: 2004/04/21 02:05:33
Author: christos
Branch: HEAD
Tag: (none) 
Log:
Replace the statfs() family of system calls with statvfs().
Retain binary compatibility.

Members: 
        main.c:1.17->1.18 

---------------------
(which would be incompatible with my 2.0 kernel, I guess).

And it repairs the filesystem without problems. Thanks!
