Just to note,
I have nvidia, and yet have the same bug. I reverted this commit - didn't help.
I get lots of ACPI: Failed to switch the brightnes when I press hardware keys that change brightness (even these sometimes don't work)
the /sys/class/backlight is empty
2.6.29 works fine.
Best regards, Maxim Levitsky
