Bug Description
This is a spin-off of bug 406515, which was hijacked to be about Lenovo-only. So this one is about Macbooks.
In Karmic the FN Brightness keys don't work in KMS mode; all other fn keys still function as intended.
If I disable KMS via boot parameter "nomodeset", the fn keys work again. I do not have any files in /sys/class/

status: | Incomplete → Fix Released |
The fix proposed in the other bug (kernel parameter acpi_backlight= vendor) does not fix things on the MacBook4,1 by the way. Just one more datapoint (as as the attached apport data is showing that as my current kernel parameter :-))
