> Is this regression?  Did the backlight used to go off in a previous release?  
For me, the problem has always existed. But before, I used the PBButtonsd
daemon (http://pbbuttons.berlios.de/). This daemon switched off the backlight
putting the level brightness to zero. 
But I think the radeon driver should switch off the backlight alone without an
other daemon because all "power manager" programs (like gnome-power-manager)
use the DPMS features to control the switch on/off display. 


> I suspect apple has the backlight wired up some non-standard way.
Yes, I agree with you. I also read about this on internet but I can't find the
article again. 

How can I help you to find a solution ?
