No, I used the sources from the ppa repository. I can test my patch with 
the git head as well, if you want.

Yes, this works great. I also tested suspend/resume (mbp-nvidia-bl 
related): works also great - the last setting is restored even though 
you can see that brightness is briefly (less than a second) turned to 
maximum.

During my suspend/resume experiments, I noticed that pommed sometimes 
(but only after the resume) stops to control the keyboard backlight: 
using F5 and F6 doesn't work anymore until I restart pommed.. strange:

The keyevents arrive..

This is after a restart of pommed (and where it works again):

and that's my config - in case I set something stupid:
