Things that work:

1. USB

2. Sound (External Mic is not working but i can live with that)

3. C-States & P-States (Generated by Chameleon)

4. Graphics (Generated by Chameleon)

5. Keyboard & Touchpad (Installed by multishit, ACPIPS2Nub.kext & ApplePS2Controller.kext)

6. FireWire (I am not sure if someone tests it please give feedback)

Things that doesn't work:

1. WiFi (if i remember by default it comes with Intel 3945abg i have replaced with BCM4311. Work Natively for both Mac and Windows)

2. Ethernet (I don't really need it but i thinks there is a kext out there which works just fine)

3. Camera ( I don't think it will ever play)

4. Card reader (Same as the above)

5. Sleep (Same as the above)

4. Brightness keys ( Althought the Fn+Right,Left control the screen brightness the mac notification (Sun) doesn't comes up)

Regarding SMBios.plist currently i am staying with MacPro3,1 cause it's the one with the better performance everything else i tried (MacBookPro3.1,MacBookPro4.1, MacBookPro5.1) it's a performance drop. Anyone with any Hints & Tips for this is more than welcomed...

As a conclusion if everyone has a suggestion or a solution or a query please post so we can achieve better compatibility for this laptop!
