This bug is not related the Gateway computer, it happens also with my new Acer Aspire that has the same Core i5 430m with Intel Integrated Graphics.
I am using vanilla Kubuntu 10.04. As Tony mentioned, the OSD appears and the FN keys are working. But the screen brightness is not changed. I also tried to set it directly as Tony did, writting to /proc/acpi/video/GFX0/DD02/brightness. Doing this has no effect on the screen brightness, all other /proc/acpi/video/GFX/DD0X folders have brightness files indicating "<not supported>".
The FN keys do change this proc file that I mentioned before, but again, nothing happens.
As Tony, I am a bit desperate to find a solution. I am willing to do some testing, but I am out of resources with this.

I would appreciate some ideas.
