Hi.

Replace the AppleRTL8139Ethernet.kext from the Original IONetworkingFamily.kext with the AppleRTL8139Ethernet.kext from the OSX86 site.

Location : /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleRTL8139Ethernet.kext

And then
Put your modified IONetworkingFamily.kext into /S/L/E.
Run "Kext Utility".
Reboot.

I am using a 10a432-64bit mode. ( ASUS P5K[ICH9] + Chameleon2 RC3 r658 )
