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.
