forgot to add the '.ko' to the end of the module filename.

# From: @(#)bsd.prog.mk 5.26 (Berkeley) 6/25/91
# $FreeBSD$
#
# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
# drivers (KLD's).
#
#
# +++ variables +++
#
# CLEANFILES Additional files to remove for the clean and cleandir targets.
#
# DISTRIBUTION Name of distribution. [bin]
#
# KMOD The name of the kernel module to build.
#
# KMODDIR Base path for kernel modules (see kld(4)). [/modules]
#
# KMODOWN KLD owner. [${BINOWN}]
#
# KMODGRP KLD group. [${BINGRP}]
#
# KMODMODE KLD mode. [${BINMODE}]
#
# LINKS The list of KLD links; should be full pathnames, the
# linked-to file coming first, followed by the linked
# file. The files are hard-linked. For example, to link
# /modules/master and /modules/meister, use:
#
# LINKS= /modules/master /modules/meister
#
# KMODLOAD Command to load a kernel module [/sbin/kldload]
#
# KMODUNLOAD Command to unload a kernel module [/sbin/kldunload]
#
# NOMAN KLD does not have a manual page if set.
#
# PROG The name of the kernel module to build.
# If not supplied, ${KMOD}.o is used.
#
# SRCS List of source files
#
# SUBDIR A list of subdirectories that should be built as well.
# Each of the targets will execute the same target in the
# subdirectories.
#
# SYMLINKS Same as LINKS, except it creates symlinks and the
# linked-to pathname may be relative.
#
# DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)
#
# MFILES Optionally a list of interfaces used by the module.
# This file contains a default list of interfaces.
#
# +++ targets +++
#
# distribute:
# This is a variant of install, which will
# put the stuff into the right "distribution".
#
# install:
# install the program and its manual pages; if the Makefile
# does not itself define the target install, the targets
# beforeinstall and afterinstall may also be used to cause
# actions immediately before and after the install target
# is executed.
#
# load:
# Load KLD.
#
# unload:
# Unload KLD.
#
# bsd.obj.mk: clean, cleandir and obj
# bsd.dep.mk: cleandepend, depend and tags
# bsd.man.mk: maninstall
#
