moving keymap configuration out of xorg.conf

[Julien Cristau <jcristau@debian.org>]

Hi,

in order to make input-hotplug work with non-us keyboards, we need to
move the keymap configuration from xorg.conf to hal.
The way this is done in Ubuntu is to have that config
in /etc/default/console-setup, which is used for the console, and have a
callout script which runs on hal startup and reads that file.

So I'm thinking that we need to:
- have console-setup try to read xorg.conf on initial installation,
  and get its settings from there
- have xserver-xorg depend on console-setup
- remove the keymap configuration from xserver-xorg.postinst and
  dexconf
- profit!

In order for d-i to use console-setup, someone also needs to work on its
i18n.  I don't know if this is a prerequisite for X depending on
console-setup, or if we can start this right now.

Thoughts?  Things I forgot?

Cheers,
Julien
