Tim & I have different beliefs here.  Tim believes that if something
works on one flavor of Windows, that says nonthing about the other
flavors.  I believe that when it works on one flavor, you can assume
that it works on all, unless proof to the contrary is shown.  I'm sure
we both have experience to back this up. :-)

If you could get Python from CVS, build it with MSVC 6.0 for Windows
(elaborate instructions are in PCBuild/readme.txt!!!), and see if the
bz2 module works on all flavors of Windows to which you have access,
that would be tremendously helpful IMO.
