I have the very similar board, as all the (x)P-35(x)-DS-(x) are typically very very similar. This board is great for 100% vanilla install, also works great with vanilla IONetworkFamily. You don't have to completely remove it. If you want to use psystar's R1000 kext (which is better for this particular ethernet chip) just install it. Also you can restore your origianl ionetworkfamily.kext.

If you want, go and extract your DSDT table. You can do it with getDSDT.sh from within DSDT patcher

you don't have to make the patched dsdt, just extract it and send it to me. I will patch it for you, add TimeMachine fix, make your LAN as built-in and also can add your Graphics and Audio. After that you can remove all injector kexts like NVinject or NVKush, ALCInject ... Also mackerintel added great option to chamelon, smbios fix, so you can have it together with dsdt override option and use vanilla smbios.
