# TODO 
#	* handle commented out "PciOsConfig"
# 	*? status/ ext-status
#	- show config
# 	- check wether curr. configuration matches setup ? 
#	- make it work when hotplug files not installed ?
#	  ( currently it will just inform that they are not installed
#	  and exit )
#
# $Id$
# - don't exit silently if hackvideo or modules loading is deactivated,
#   run the script to the end
# $Id$
# - show keyboard status per VT ,use sed instead of head(head is in /usr)
# - *? status/ ext-status
# - (mice & evdev links)?
# $Id$
# - include hackvideo handling (long time wondering what was missing)
# $Id$
# - got it actually running
# - use >& /dev/null to load variables from the config file 
#   (what a mess)
# $Id$
# - initial release
