[SciPy-Dev] Iterative Least Squares for Sparse Systems

Hello,
I've noticed a trunk project at
  http://projects.scipy.org/scipy/browser/trunk/scipy/sparse/linalg/isolve/lsqr.py
This looks like a very useful piece of code - anybody know the status
of including it in a scipy release?
I ask because I need to find a solution of a very large
over-determined sparse linear system.  I suppose I could just use
scipy.optimize.leastsq on a function which returns the residual, but
that seems a bit hacked.  Is there a better way to do this at present?
