The options did compile for me. I am not sure which options did not com
I am not lying. I can post my tree (or you can revert all max's changes, 
to trap.c, *machdep.c, etc.). You can then change the GENERIC kernel to read:

    options         EXEC_AOUT       # required by binaries from before 1.5
    options         COMPAT_NOMID    # NetBSD 0.8, 386BSD, and BSDI
    include         "conf/compat_netbsd09.config"

Commenting out:

    include        "conf/compat_netbsd15.config"

You can then download the netbsd-1.0 tree and try it.
I also put my lisp binary in http://www.netbsd.org/~christos/lisp
 
I am not saying we should keep the compatibility thing going forever, but
removing it should be done with a concious decision and announcement.
