You will probably need the core, functions, solvers (or at least the parts of solvers that you want to support), and integration. You'll aslo probably want the parsing module, as I noted.
You will actually find that the modules are more interlinked than you might expect. For example, the functions module relies on the ntheory module to evaluate some functions at numeric arguments (e.g., perfect_power is used in log.eval()). There is a little graph of the dependencies of the modules in SymPy at http://code.google.com/p/sympy/issues/detail?id=2103 (see the one from comment 7). This may not be up to date, but I provide the code to regenerate it. You'll see from there that you will probably need to convert the polys (this is almost as essential as the core for some operations), the logic and assumptions modules, which are used for assumptions (I wouldn't recommend trying to remove assumptions from the code), you'll need the matrices and simplify for the solvers and integration modules (and perhaps other things as well), and you might need some stuff from utilities (which shouldn't cause too many problems with pyjamas, I would think). You can probably get rid of tensor by limiting the scope of which functions you want to support. If you just want to get Symbol('x') to work, you should start with just the core, and work your way up from there. You can get a rough idea of which modules are the most important by looking at what order they are imported in sympy/__init__.py, since the ones that the others depend on have to be imported first.
