Bug Description

Hi, I have a DV2058ea laptop, not sure what other laptops in the series would be affected by this. I previously installed Ubuntu Hardy Heron Beta on my laptop (the last beta I think), I could adjust the screen brightness and it worked perfectly (I think I was using 2.6.24-12-rt)! A kernel upgrade broke my Ubuntu install so I decided just to abandon it.

Yesterday I installed Ubuntu Hardy Heron LTS (Release Candidate) but sadly screen brightness can't be adjusted, I can confirm this is with or without the NVidia drivers.

Would love this to get fixed, it's never worked properly since I first installed Edgy, I think it kind of worked in Edgy and Feisty (2 levels of brightness and buttons had to be pressed repeatedly), but didn't work at all in Gutsy.
