Bug#402584: kernel: [ACPI] brightness controll on laptop don't work since 2.6.18

[Maik Erling <maikqwertz@freenet.de>]

Package: kernel
Severity: normal

Since kernel version 2.6.18 i can't control the brightness of my laptop
anymore. It is a Fujitsu S7110 and brightness is set by a combination
with Fn-key. Other Fn-keys-combinations work properly. With acpi=off
brightness controll works fine. With Kernel 2.6.17 brightness controll
worked with enabled acpi.

Thank you.
