Display dimmed down after resume

Hi,

I got myself a Fujitsu-Siemens Lifebook P7120 this weekend. Fantastic
laptop. And with Ubuntu Dapper, (almost) everything works. I have yet to
make suspend work on a self compiled kernel, but Ubuntu almost manages
it. 

My problem is that after resume, the screen is totally dimmed down. I
have to use Fn+F7 to get light again.Anyone have an explanation for
this? Or even better, a solution :D Else, echo 3
> /proc/acpi/video/GFX0/LCD/brightness gives: "echo: write error:
Invalid argument". Guess it's unsupported on this machine?

Hope this is the right list for this.

Best regards,
Stian
