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.
