Hi! After updating my BIOS and suspending, my computer is broken and heading to the service center as soon as possible, so I cannot answer everything, but as much as I can respond:
1) Not working in 185.13
2) 3) Updated, VDPAU did not work and after suspend :-P
4) Yes. Suspend/Hibernation never worked on my PC in Linux(the only thing, but really useful)
5) I tried every combination. I cannot test SSH so far, I will do it as soon as my laptop will be repaired.

By the way, it should be good idea to lock the thread above and the threads, that complain about this bug and left just this, where are you asking about circumstances?
