Are you certain it's a linear system?  I'm not.  If it was a matter of
minimizing a linear expression subject to some set of linear
equations, then we could model this as a Linear Program for which
there are some perfectly good solvers available.  (Few with BSD-style
licenses, but we could probably get some insight out of running for a
while with something that's there...)

I think there's good reason to consider it to be distinctly
NON-linear, which makes it way more challenging to solve the problem.

There might well be some results to be gotten out of a linear
approximation; the Grand Challenge is to come up with the model in the
first place...
