Similar problems on a Lenovo 3000 N100 0768FPG.

I can only set my brightness correctly with:

cat $level > /sys/class/backlight/acpi_video0/brightness

and then entering a number between 0 and 100.

There seems to be a patch here that works for someone:

When I type:

cat $level > /sys/class/backlight/acpi_video0/brightness

I get this:

levels:  100 57 0 14 28 43 57 71 86 100
current: 0

despite having just set it at 100.
