Hum... something like the following (completely untested!) should do the
trick:

  cd /basedir
  mkdir codebase; cd codebase; git init-db
  for version in 1.0 1.1 1.1a 1.1b 2.0.0 ...; do
     cd /basedir
     tar xf tarball-$version.tar
     mv codebase-$version/* codebase    # Take care to move everything!
     cd codebase
     git add .
     git commit -a -m "Updated to $version"
     rm -rf *                  # Delete everything except for git stuff
  done

Files that don't change will be recorded as is (git tracks contents).

You can let GIT_DIR point somewhere outside the extracted directory.

If the dates of your tarballs are meaningful, you can use something like
this:

export GIT_AUTHOR_DATE="$(date --reference=foo-1.1.tar +%s) -07:00"
