I am currently working on different projects, but I will try to do my best to help with this (but just might require more time than I would otherwise need). Given the scale of the task and the amount of testing required, I expect that it will take a while to get a complete set of patches reviewed and tested which should hopefully be enough to fix support for all platforms affected.
