Thanks for catching this.

Can you please request this change to be pulled up to the netbsd-2-0
branch?  The patch looks ok to me.

How did you uncover this problem?  I've been interested in testing
filesystems with large numbers of logical blocks by creating a 2tb
ufs2 filesystem with a 512 byte fragment size, but haven't yet done so
myself.  Do you know if there are other problems lurking for that
case?
