git-repack starts at your heads and works its way down. You can either:
  - make a dummy commit for a tree with all of your blobs:
    $ while read sha1; do
        echo -e "100644 blob $sha1\t$sha1"
      done <list_of_sha1s | git-update-index --index-info
      tree=$(git-write-tree)
      commit=$(git-commit-tree $tree)
      git-update-ref HEAD $commit

  - call git-pack-objects directly with a list of objects
      git-pack-objects .git/objects/pack/pack <list_of_sha1s

Obviously the latter is simpler, but the former will also make
git-fsck-objects happy. Note that they're both untested, so there might
be typos.
