If you have Mathematica 4.2 and time constraints are not too severe (i.e. the system contains not too many equations and variables), simply reformulate the root finding problem as a maximization problem and use NMinimize. The reformulation is simple: just minimize the constant function 1 subject to your equality and inequality constraints.
