Some more data for you @admin – i used TM to downgrade back to Yosemite, and everything works fine. Can adjust brightness, comes out of sleep just fine, etc. Happy to help test if you need any data, etc. from my end. Definitely know that my posts are intended to help and are in no way complaints. You saved my ass with your R8911 solution!
