Our group has developed PySUNDIALS
(http://pysundials.sourceforge.net), which is a Python package
providing bindings for the SUNDIALS suite of solvers (using ctypes).
SUNDIALS has a DAE solver (IDA), which should be able to handle your
kind of problem. The PySUNDIALS distributrion comes with examples for
each of the wrapped solvers.
