Fujitsu-Siemens Esprimo X9525 Brightness Up hotkey

Hi everyone,

I’ve just finished installing OpenSUSE 11.1 on my Esprimo laptop. Everything seems to work quite fine. The only thing that is not working at the moment is the Brightness up hotkey (Fn+F9). This is very strange as the volume keys, the mute key and the brightness down key work perfectly. For the volume hotkeys I’ve got even a nice volume splash icon showing up on the screen.

Doing an acpi_listen I get:

video LCD0 00000087 00000000 for the Brightness down hk (working)

video LCD0 00000086 00000000
video LCD0 00000087 00000000 together for the Brightness down (not working).

Any clue?
