Millstein on Corporate Boards

Given that Corporate Boards are the immediate authority tasked with supervising and guiding a company's management one could argue that dysfunctional boards are the root of all evil in the corporate world.
So I have some sympathy with the general drift of this article (Fortune, What's behind Corporate Scandals?) but one is also left with the feeling that while we can easily point to problems it is much more difficult to come up with solutions.
General exhortations for boards to become 'better', more 'hard-working' etc are very well, like Sunday prayers, but they are of no practical use.
Any suggestions?
