Good info.

I checked in system profiler to make sure the R1000.kext wasn't loaded.

The AppleALC8169Ethernet.kext is loaded though, and that's how I'm getting ethernet connectivity.

The AppleALC8168Ethernet.kext is located in the plugins folder of IONetworkingFamily.kext.

You said I could edit the .plist of a legacy kext to get bonjour working? If so, could you elaborate so I could try that?

If not, I do have the R1000.kext from psystar and haven't seen it load into the extensions in system profiler. Would that be because the AppleALC8169Ethernet.kext is already loaded? How could I get the R1000.kext to load first. Would I have to remove the AppleALC?
