One suggestion I would make would be to modify the bench_str benchmark to only benchmark the printing time, not also the time it takes to expand the expression. You may also similarly want to factor out the creation of symbols, though that should be negligible.
Regarding the completeness of the benchmarks, I would consider adding benchmarks for the polys and the matrices. None of the ones you have really use the polys extensively (unfortunately, nether expand nor integrate use the polys at this time). A common benchmark is something like factor(expand((x + y + 2*z)**10)) (except again factor out the expansion from the timing).

Right now, SymPy is painfully slower in pypy than in CPython (this is seen when running the test suite, for example). But we would like to have an actual speedup, like other projects have reported having. Perhaps it would be worth it to look at the test suite test by test, and see which ones are the slowest in PyPy compared to CPython, and then create some benchmarks based on that.
