Public bug reported:
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/backlight. Other debug output was
reported in bug 406515, let me know if I can give you more information.
This has been occuring since at least early Karmic alphas until now
(2.6.31-18-generic).
