Comment 12 for bug 625770

I've tried to manually patch the udev files in my Maverick installation but the brightness keys still don't work... :(
I've clearly rebooted the machine.

I report few details on the modified files:

$ ls -la /lib/udev/rules.d/95-keymap.rules
-rw-r--r-- 1 root root 9919 2010-11-12 18:04 /lib/udev/rules.d/95-keymap.rules

The involved part of 95-keymap.rules:
