I had similar problem with windows 7 x64 on T4446 , I could not adjust brightness for a few month. . But fortunately today I found Intel had its own Graphics Media Accelarator Driver for windows 7 that does the trick, no hotkey though. Here is the link to intel's driver:

I have a G530 Type 4446 which had a dodgy version of Vista because a techy at my daughters school loaded Business over Home Premium ... no!! After trawling the Lenovo site I was convinced that the machine would take W7. Alas I got the hotkey problem whereby the Fn F10 and Fn F11 keys were non-functional. Rang Lenovo tech support and was told a number of stories, all pointing to the view that the machine was designed for Vista. I trawled some more and came across this: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70994
As a very helpful Lenovo techy had already tried all of the possible energy management drivers I decided to give it a go. I was a little reluctant to play with the BIOS but I kept it on mains power, closed all other programs and ran the app.
Presto! Brightness hotkeys now work. As for the sleep and network hotkeys - well, I can live without them.
Pleased to be of help to all you other G530-4446 W7 users. Let me know if it works for you.

Addendum to above post:
Have just tried the link in above post and it is dead! You need to update the BIOS from v 1.09 to v 1.10. It is somewhere on the Lenovo site. The file is called 6get19ww.exe

This is a way what is I know. But it's not pratic, we want a real solve.
For your reference: G530 4446 screen resolution is not the native 1280x800 - fix released
Hope this helps.
