FZ21Z brightness keys do not work under Windows 7

Did a clean install of windows 7 on my sony vaio fz21z laptop. Cannot find a solution to get the brightness keys working also found driver for bluetooth that works fine but cannot turn the device on or off. I have been told that it is a separate piece of software but cannot find this. Please can anyone help me.

Windows 7 Ultimate x64

I've tried a few solutions to get the FN keys working, but found out long ago that they don't work unless you use the original graphics driver, even on Vista.

I've tried a few solutions which requires some of the Sony software to be installed, but none seem to work, but as they aren't that important to me, I'm not too bothered.

The x64 bluetooth driver came from HERE, driver number EP0000154872, and that one will allow you to turn it on and off.
