As far as I can tell, this is not possible to do directly with a single command line; you'd have to do something like Justin Lilly suggests and then run 'git log' on the resulting list of hashes, e.g.,

for h in `cat good-hashes`; do
    PAGER=cat git log -1 --pretty --stat $h
done

should do the trick.
