Windows 8 Driver Problems

Ok, I know that Windows 8 is not supported yet for all MacBooks, but I am sure that many people have got Windows 8 up and running.

I only have two problems I am facing currently - Brightness and Audio.

All the other stuff work like a charm.

In the CHARMS Bar, the audio slider reads "Disabled" and if you move over it, it says "No audio output device is installed."

The brightness bar says "Unavailable" and the move over text is "Windows can't adjust the brightness of this display"

I have set the adaptive brightness off BTW.

I just need 2 drivers to get this working. Can anyone help? Thanks in advance!!
