Ok, I've updated a second ago. Everything works (well... I had to put back my copy of stuff from System/Library/Extensions and use Kext Utility to get sound working), no problems with webcam (video is still upside-down but... I can survive :P), the only issue I found is battery. Status is totally messed up. If I unplug the charger it says e.g. 1h 50 min but after a sec - 2h 10 min, then... 1h 30 min >.<" Anyone willing to make a new version of AppleACPIBatteryManager? ;-)

PS Can you tell me if 61 Celsius is ok temperature for CPU? iStat says 61 for CPU A and CPU B >.<"" (I am using only firefox at the moment...)
