updated incorrect assumption in bug description, reflecting my post
above.
** Description changed:

gpm Version: 2.21.92-0ubuntu2
- On my Dell Inspiron 1501 laptop brightness keys work fine because they are
done in hardware (bios 2.6.3), but dim on idle/battery does not work. I
narrowed it down to the following method in addon-dell-backlight.cpp not
working (or the libsmbios function it calls):

hald gives the following messages

dcdbas kernel module. Please make sure it is loaded
The 'dcdbas' module is loaded according to lsmod (and read_backlight
- does work). When this is fixed, gpm also needs to respect
- "laptop_panel.brightness_in_hardware = true' (which is set on my
- laptop). ie, keypresses should not result in "SetBrightness" dbus
- calls. Right now it does send them (according to the change log way back
- in early 2006 it was supported, but it seemed to be ripped out when
- files where reorganized. There is still some code (in gpm-brightness-

- picked up by gpm-brightness-lcd.c, but there is no code for ignoring
- keypresses here.

- Note the that gpm needs to process the keypresses to show the osd (just
