So, in my experience, the easiest way to confirm if something works
with PyPy (when you can't find proper bibliography in the web) is to
try to install it in a pypy virtualenv [0]:

(my-pypy-env)nessita at dali:~/projects/pypy/my-pypy-env$ pip install protobuf
Downloading/unpacking protobuf
  Downloading protobuf-2.4.1.tar.gz (56Kb): 56Kb downloaded
  Storing download in cache at
/home/nessita/.pip_download_cache/http%3A%2F%2Fpypi.python.org%2Fpackages%2Fsource%2Fp%2Fprotobuf%2Fprotobuf-2.4.1.tar.gz
  Running setup.py egg_info for package protobuf

Requirement already satisfied (use --upgrade to upgrade): distribute
in ./site-packages/distribute-0.6.24-py2.7.egg (from protobuf)
Installing collected packages: protobuf
  Running setup.py install for protobuf
    Skipping installation of
/home/nessita/projects/pypy/my-pypy-env/site-packages/google/__init__.py
(namespace package)

    Installing /home/nessita/projects/pypy/my-pypy-env/site-packages/protobuf-2.4.1-py2.7-nspkg.pth
Successfully installed protobuf
Cleaning up...

(my-pypy-env)nessita at dali:~/projects/pypy/my-pypy-env$ pypy
Python 2.7.2 (341e1e3821ff, Jun 07 2012, 15:38:48)
[PyPy 1.9.0 with GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``Python 2.x is not dead''
>>>> from google.protobuf import descriptor

Seems to work :-) (though I have no app using it right now).

Cheers, Natalia.
