A simple solution to the issue where the arch is missing some programs
is the version I see in the xserver-xfree86 script:

  #!/bin/sh

  PATH=/sbin:$PATH

  if which lspci > /dev/null 2>&1; then
    LC_ALL=C lspci | grep 'VGA compatible controller:' >&3
    LC_ALL=C lspci -n | grep 'Class 0300:' >&3
    printf "\n" >&3
  fi

If the 'grep' part is dropped, this would work for discover as well.
And the (sub-)archs needing other programs can detect their existance
the same way. :)
