I suggest redirecting the results into a cachefile, because the extraction is pretty slow.

srcsysmod_kmod() {
  tab="$(printf "\t")"
  (
    cd /usr/src/sys/modules
    find . -type f -name 'Makefile' | sed -e 's#^\./##' | xargs dirname | sort | while read dir
    do
      # Slower but more precise
      #kmod="$(make -C "./${dir}" -V KMOD)"
      # Faster, but might be incorrect if the makefile does voodoo
      makefile="${dir}/Makefile"
      kmod="$(sed -e "/^KMOD/"\!"d; s/^KMOD[ ${tab}]*=[ ${tab}]*//" "${makefile}")"
      # Format and display the results
      [ "${kmod}" ] && echo "${dir}${tab}${kmod}"
    done
  )
}
