One can try porting the BSD Auth code from OpenBSD.  I have not yet  
tried that myself.

Perhaps not without building yourself from source.  :-)

However I seem to be doing fine without PAM in my netbsd-4 systems.

I use the following settings in my mk.conf (plus there should be some  
changes to some makefiles and to the sets lists, but I haven't got  
around to them yet):
        MKPAM =         no
        USE_PAM =       no

I'm not sure it would make sense to have them integrated together into  
the same system.  In my estimation they can't really both be there in  
the same build (certainly not for anyone who wants the full and  
guaranteed privilege separation offered by BSD Auth), and with a  
compile-time option the non-default one is sure to bitrot.  Previous  
discussions resulted in nothing really and PAM was blasted into the  
tree without taking into account any technical considerations.  Lame  
excuses were given that somehow BSD Auth could be implemented as a PAM  
module after PAM was fully integrated, but of course that blows one of  
the main benefits of BSD Auth right out of the picture (true  
guaranteed privilege separation).
Personally I think since OpenPAM is already well supported as a stand- 
alone project it should be they who provide an optional patch to apply  
to NetBSD for those system integrators who wish to offer PAM instead  
of BSD Auth.  :-)
