I had the following problems (mbp6,2 + ubuntu 11.04):

no backlight control
no notifier-popup which usually shows that pommed is running/working

Then I noticed that (the standard) nvidia_bl was not loaded. I loaded it with sudo modprobe nvidia_nl.
Now the pop-up (on the upper righthand side of the screen) 'worked' again, but no change in brightness.

I stopped pommed (sudo service pommed stop) and ran it manually with
debug mode which shows that it adjusts the level from 0 to 2047 when
hitting F1/F2 (or Fn-F1/Fn-F2 if you have fn-mode set to 2 in
/etc/pommed.conf).

similar, pommed -f showed it was happy with what it found (no backlight
complaints).

I reverted to mbp_nvidia_bl as a test and this worked:
uninstall the nvidia_bl in 'synaptic package manager'.
go to the repository in the 'settings' menu there and add the old maverick repository for mactel:
click on add in the 'other software' tab and fill in 'deb http://ppa.launchpad.net/mactel-support/ppa/ubuntu maverick main'
back in the main window of the synaptic package manager you 'reload' and install the mbp_nvidia_bl

After a reboot, you first have to check whether mbp_nvidia_bl is loaded.
(otherwise do 'sudo modprobe mbp_nvidia_bl')

My /etc/X11/xorg.conf does not contain the extra option (commented out):
    #Option        "RegistryDwords" "EnableBrightnessControl=1"

I don't have a '_bl' anymore in the blacklists:  'grep bl
/etc/modprobe.d/*' gives nothing.

MY RESUME FROM SUSPEND IS NOW MUCH FASTER!!!!!
