Ok, I played around with it some more. It seems that on my Laptop the
firmware sends out notifications on Fn+F6/7 press.
Kernel 2.6.23-rc2 worked fine, -rc3 is broken. Reverting ec.c in the
current Fedora kernel to the version in 2.6.23-rc2 makes brightness
control work again. After finding that, I tried the current HEAD version
of ec.c - unfortunately to no avail.
2.6.23-rc3 doesn't show up the (unwanted) key events for Fn+F6/7 though
- this behaviour was introduced in -rc4.

Is it possible to fix the problem with the amount of information
provided? If no, what additional information can I provide?

Thanks,

Danny
