I'm a little surprised that no one has mentioned this possibility, but I think it is worth considering, as it may change how you are thinking about the situation.
Since your original easy and straightforward solution to the problem only worked for a year, is it possible that the management (this new guy or maybe someone above him) has already explicitly decided that they want a different, more permanent solution to the problem?
For me, the fact that 1) you were not invited to the original meeting and 2) they did not pick up the solution that you said already worked makes me wonder how well it really worked in the first place and whether they weren't trying to "save you some face" as we say in China.
If I were you I would not make the changes on Monday without first discussing with the new manager. Note that you want to do what you can to improve conditions for the company and that you have a solution that you think will resolve the problem, at least temporarily, while they work out a more longer term fix. Indicate that you are available to help work out that longer-term fix if they feel that would be helpful to the team, and assuming the rest of your workload can be adjusted so that you can do this on regular hours. And indicate that if there is a reason you feel the original fix was not up to standard, you would like to know that and get feedback on what they think you could do to improve your approach to such things.
By approaching it this way, you kill multiple birds with the same stone. YOu open up the floor for dialogue with the new boss, you let him know you have certain skills and are willing to apply them wherever the company needs them, and you show that you are interested in/open to constructive criticism. All done transparently, while clarifying some of the boundaries that are important to you.
Good luck with it. If it were me, I would just try to hunker down and do my job as outlined in the job description, helping out with other things when asked but avoiding volunteerism. Not because I don't agree that it is best if you try to apply your skills wherever the company needs them, but because in THIS particular environment it doesn't look like it is going to be understood/appreciated. You are sticking your neck out and probably making more enemies than friends if you are making it look like other people are incompetent and can't do their jobs. That is a sad kind of situation to be in, especially when you have had a good boss who supported you in the past, but four years is not so long and if you can hang on and weather through this it may be easier than trying to work another transition.
You might be very good as a consultant, though, if there is a market for your services and special skill set. Consultants are supposed to know everything, and they get paid big bucks for it!
Good luck,
