ok just booted as a macbook 5,1. Everything works as before but to be honest, i don't see any difference to the macbook4,1 smbios performance-wise. I'll keep trying with different smbioses though until i reach perfection.

ok so i just did a little dsdt edit following your instructions and you are correct. Now it shows that i have an Nvidia Quadro 140m NVS. Yipeeee!!! Off to do the MB5,1 tweak, hope that goes well too

hey there victoryo, I've got the exact same system (except C2D 2,0Ghz) and also noticed the sluggish graphics. First of all i lowered the resolution to 1600x1000. That seemed to improve things a bit. Secondly i did the fakesmc & smbios technique. Best i could do is to use a MacBook 4,1 smbios without sleepenabler/nullcpupowermanagement/vodoopstates. Everything still works and to my opinion it feels a bit crisper to respond, cpu throttling is faster and graphics a bit better. My Gpu is also shown as 8400M gs but frankly, i couldn't care less so long as it works. I believe it can perform better maybe with a MBP 5,1 smbios but i get kernel panic when i try that. i think it might be the fact that MBP5,1 used ddr3 memory and different FSB than what i have. Maybe someone else could advise on this matter?
