for your ethernet go to realtek they have their own mac drivers that should work no problem. The best option for graphics card is to turn of shared memory in the bios as this will stop it from booting even in safe mode when you have installed the right drivers. For the sata dvd drive you need an improved kext for your chipset or try using sata or ahci or ide mode in the bios.Also i notice you have 4gb of memory to run this stable you will need the latest nforce chipset kext its on insanelymac in the drivers section otherwise you will keep getting random panics.

Hope this helps
