struct lfs in ufs/lfs.h claims to be 512 bytes long. However, since
the m68k compiler seems to be content to align long-words to word
addresses, the structure is only 510 bytes long. What's it like on
a 386 or Alpha?
Get newlfs, put it under gdb and do a sizeof(struct lfs).
I have a couple of ideas but I'm not sure they will work on all achitectures.
