I'd suggest using Cython for bindings, and taking a look at scikits.sparse:

It has quite complete Cython bindings for CHOLMOD:

Not only does this give an example of using Cython to work with sparse
matrices and Tim Davis' code, there's a fair amount of infrastructure
that can probably be re-used -- I believe that KLU relies on CHOLMOD's
data structures for basic sparse matrix tasks. If you'd like to
contribute your work to scikits.sparse, then we can factor this out
into shared code.
