I think that behavior - which I also experience - is due to HAL, which seems to have gradually taken over more and more of the hot key stuff. The problem is that the supplied addons for macbookpro only work for some models up to 3,1, and only barely. This bug seems relevant: https://bugs.launchpad.net/ubuntu/+source/hal/+bug/226894
