Unknown Device Annoyance in SONY VAIO Laptop Reinstallation

I did a clean vista ultimate installation on a VGN-NR330e SONY laptop. Then it took a while for me to search online for the one last driver: Device Manager reports it as "Unknown Device", and its property indicates the location at Intel ICH8M LPC Interface Controller.

I came across the solution online, which said the missing driver on similar product but a different model being a "SONY Firmware Extension Parser". Somehow the blind spot in Sony's driver page just wasted my time looking for this and even tried to give up assuming this is the solution and looked for other solution. But then I came back and found what I was looking for at the same page NoteBook Control and Utilities category.

And Voila! Case solved.
