Ugh.

I looked at this in more detail.  Based on my 1.4T source tree:

Longer passwords are supported, but for passwd(1) to set them you have
to build it with NEWSALT defined.  Add -DNEWSALT to CPPFLAGS in
usr.bin/passwd/Makefile and rebuild and reinstall passwd.

Why NEWSALT isn't defined by default I can only guess.  I would guess
it is for the sake of compatability with other OSes that still use the
antique password hashing algorithm - which really doesn't make any
sense unless YP is in use.

Alternatively, you could write a tiny program to call crypt(3) with a
suitable salt string to get a new password hash, and install that in
master.passwd by hand.  Ugly, but perhaps workable if you don't need to
change your passwords that often.
