Comment 2 for bug 281951

I've created a file named /usr/share/hotkey-setup/acer-aspire-5900.hk (contents below) and added the following lines to /etc/init.d/hotkey-setup so that it gets loaded:
     Aspire\ 59*)
     . /usr/share/hotkey-setup/acer-aspire-5900.hk
     ;;

Result:
1. While booting (e.g. in recovery console) hotkey-setup is not loaded yet, so keys don't work correctly.
2. Later in the boot process, hotkey-setup is called (I've put some debug "echo" instructions to verify this).
3. When gdm is loaded, some other setkeycodes are executed (I don't know who does that, maybe X?) which override hotkey-setup, and keys again don't work properly.
4. When the gnome session is loaded, yet other keycodes, different than those of gdm are loaded (maybe by gnome?) which override all the previous.

So I think that modifying hotkey-setup is not the correct way to solve this problem. Could someone please give us some suggestions on what else to look for?

Should /lib/modules/2.6.27-7-server/kernel/ubuntu/misc/acerhk.ko be loaded? (it's not)
Should I also modify /usr/share/X11/xkb/keycodes/evdev ?

If I manually run "/etc/init.d/hotkey-setup restart" anytime, either on console or on X, keys work fine.

The file /usr/share/hotkey-setup/acer-aspire-5900.hk I've made:
