We need a new legacy kext (see AtherosFix.kext from netkas.org). This new kext is compatible with all the previous versions.
This update slowed down my system and broke atheros wifi support.
I had to restore /System/Library/SystemConfiguration/Apple80211Monitor.bundle from 10.6.7
Edit : we need a proper SMBIOS.plist to keep 10.6.8 Vanilla (Source, Property and list )
No more C-States for me … looking for a solution …
For C-States to work on 10.6.8 I replaced /System/Library/Extensions/IOPlatformPluginFamily.kext with the one from 10.6.7
10.6.8 Update - No CPU PM - Wireless works fine - no Bluetooth (even after I rolled back to 10.6.7, Bluetooth is not working)
I updated to 10.6.8 using combo update, rebooted, no Trackpoint or Keyboard - logged into safe mode - dropped Extra folder from 10.6.7 installation into root, got trackpoint and keyboard back. Didnt check Voodoo…I will check tomorrow.
