Re: 2.6.31-rc2: thinkpad boots with backlight low

There is one thing that comes to mind: display power management.

Is anything, by chance, setting the backlight devices to low power mode
on machine restart? The backlight drivers would try to set brightness
to 0 when it cannot turn the display off for real...
