RFC: xconfig init script

Hi,

a big issue for livecds as well as for 'user-friedly' distributions is
hardware detection for x11. I was thinking about providing a nice solution
which could easily used for such systems. here is my proposal:

We add a 'xconfig' init script to the xorg package which is disabled by
default. This script first checks if one of the following condidions is
true:

	- the /etc/X11/xorg.conf file is identical to
	  /etc/X11/xorg.conf.example

	- the /etc/X11/xorg.conf file is missing

	- the /etc/X11/xorg.conf file is auto-generated by 'xconfig'

the script fails if none of this checks matches. otherwise it tries to
auto-detect the hardware and creates the xorg config (using 'Xorg
-configure' and other hacks) and loads the 'drm' modules.

The check if /etc/X11/xorg.conf is done by checking for a special comment
in /etc/X11/xorg.conf. That comment also contains a checksum for the
file (excluding the comment itself). If the file has been modified, it
the auto-generated file will be named differently and the other steps
(such as loading kernel modules) are still performed. That way it is
possible for the user to modify the config (such as altering default
resolutions) without loosing the rest of the magic.

Targets sch as the livecd could enable that init script by default. crystal
could enable it in runlevel 5 (the runlevel which automatically starts up
xdm).

What do you think?

yours,
 - clifford
