Brightness settings dont stick !

[donbaccus]

I have a new iMac 2009 - 24' - 2,93Ghz, running the latest OS.
When I start, the brightness is at maximum... I set it to minimum, only to find it at maximum again when I re-boot the computer ! I tried setting it via settings as well... it just dosent stick !
On the flip-side, the volume retains its last settings...
any ideas ?

Repair permissions and reset PRAM (http://support.apple.com/kb/HT1379).

Windows remembers my brightness settings (Boot Camp). Apple need to fix the problem soon.
