Comment 11 for bug 345318

I have modified the '90-Add-guarded-brightness-stepping-functions' patch in order to get 12 levels of brightness adjustment, and changed the formulas used to calculate the next step for decreasing/increasing brightness in order to get constant steps.
It seems to work good on Samsung NC10.
Please try it.
Or else you can get a precompiled package (i386, lpia) from my PPA:
