Thanks, I'll use that for now. The problem is, if that button will end
up only toggling the WLAN, say in a gnome desktop, there's not gonna
be an easy way to turn off the bluetooth. Which is no good when you're
on battery power.

Alright, I'll do this.

I tried it under Ubuntu as well (I'm using a 2.6.28 kernel there),
with no luck. The thing is "lshal | grep keymap" shows a correct array
of input.keymap.data, but lshal -m doesn't show anything when I press
the keys. acpi_listen, does though.

I'm just basing this on the actual 30-keymap-module-asus-laptop.fdi
file, but I might be doing something wrong. For example, if
acpi_listen says this when I press the "mute" button:
hotkey ATKD 00000032 00000016

shouldn't this line from .fdi be correct:
          <append key="input.keymap.data" type="strlist">0x032:mute</append>


I also want to say that I'm no programmer by any means, and I'm
starting to think I'm already doing things over my ability. If that's
the case, I probably won't be able to produce anything of any use for
hal, but I'll probably learn something trying :-) I'm trying to follow
the hal keymap quirk site
(http://people.freedesktop.org/~hughsient/quirk/quirk-keymap-index.html).
I hope it's still valid.
