This NV79 issue has also been referenced here: 
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/685727 
among many other places.
Only the backlight is being turned off during boot and also after resuming from 
a suspend. Using a bright flashlight shows that the video is still being 
displayed but without the backlight, it appears to be black. Lucid worked fine 
on the same hardware and there was no backlight being turned off issue.

Maverick 2.6.35-27, 2.6.35-25, 2.6.35-24 all have this issue. 2.6.32-27
Lucid works fine.
