Subject: regression since 2.6.36: backlight in sony-laptop not working

Hi Mattia, hi all,

(please keep me in Cc)

when switching from 2.6.36 to 2.6.37-rc1(+git) I realize that I cannot
adjust the backlight anymore. Before this was possible with the
Fn-F5 and Fn-F6 keys, but now nothing happens.

acpi_listen does not issue anything when these keys are pressed.

Is there any obvious oversight from my side?

config is attached.

Best wishes

Norbert
