Summary of the thread in sci.math: 

(a) The problem is badly stated; the correct statement is that there
is no closed-form solution to the general quintic using radicals.
This is not relevant for much of anything; for instance, there are
perfectly satisfying closed-form solutions using elliptic functions,
which are quite computable.

(b) The technique in the paper is a very old technique for
approximating solutions to polynomials, which doesn't work very well.
