/sys is usually a symbolic link to /usr/src/sys.  I think at least
you'll need a kernel source that is *synched* to your kernel.  Worse

no kinfo.h anywhere in the NetBSD source tree or /usr/include...

NetBSD's identd works "properly".  It's just that some IRC servers
won't be satisfied if your identd returns OS type "OTHER".  Try
removing identd "-o" option in your /etc/inetd.conf.
