Realtek ALC262 (Intel 82801G) on Leopard

I have successfully installed the sound card driver on my Leopard.
The sound card of my Fujitsu S7111 is Realtek ALC 262(TODO: Intel 8?)

Here is how:
1. Install Package on your Kalway Leopard DVD:
The package is located at "System/Installation/Packages/Azilia_out.pkg"

2. Open the terminal and type:
cd /System/Library/Extensions
sudo nano AppleAzaliaAudio.kext/Contents/Info.plist

Search "IOHDAudioCodecVendorID"

and you should find something like:
IOHDAudioCodecVendorID
0x10ec0880

change it to 0x10ec0262

3.Save and exit

4.Modify AppleAzaliaController.kext
Open terminal and type:
sudo nano AppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist

Search for "IOPCIPrimaryMatch"
You shuold find:
IOPCIPrimaryMatch
0x27d8FFFF
Change 0x27d8FFFF to 0x27d88086

Save and exit

5. Type:
sudo rm -r /System/Library/Extensions.mkext

diskutil repairpermissions /

reboot

6.When rebooting, press F8 and type "-x -v"

It should work now.
