  This note is an attempt to generalize Bolibruch's theorem from the projective
line to curves of higher genus. We show that an irreducible representation of
the fundamental group of an open in a curve of higher genus has always a
representation as a regular system of differential equations on a semistable
bundle of degree 0. Vice-versa, we show that given such a bundle and 3 points
on the curve, one can construct an irreducible representation of the curve
minus the 3 points such that an associated regular system of differential
equations lives on this bundle.
