Some remarks from reading the source code (mind I never did run the script):

- it is very inefficient to use apt-get -s in make_inventory, what
  about
	[~] apt-cache policy xserver-xorg-core
	xserver-xorg-core:
	  Installed: 2:1.6.5-1
	  Candidate: 2:1.6.5-1
	  Version table:
	 *** 2:1.6.5-1 0
	        500 http://ftp.jaist.ac.jp sid/main Packages
	        100 /var/lib/dpkg/status

- extract_lib:
  Why not use dpkg-deb -x instead of ar etc to unpack the debs?

- I am still not happy with the links setup mechanism.
  On Debian and AFAIR also Ubuntu the nvidia-glx package moves away
  the libs to /usr/lib/nvidia/libGL.so.1.2.xlibmesa and
  /usr/lib/nvidida/libglx.so.xlibmesa
  dpkg ensures that even after updating the core packages the 
  links are correct and the files up2date.

  So what I do here in the init.d switch script:
	for intel:
	ln -sf /usr/lib/nvidia/libGL.so.1.2.xlibmesa /usr/lib/libGL.so.100000
	ln -sf /usr/lib/nvidia/libglx.so.xlibmesa /usr/lib/xorg/modules/extensions/libglx.so

	for nvidia:
	ln -sf /usr/lib/libGL.so.185.18.36 /usr/lib/libGL.so.100000
	ln -sf /usr/lib/xorg/modules/extensions/libglx.so.185.18.36 /usr/lib/xorg/modules/extensions/libglx.so

  and that's it. THe point in having libGL.so.100000 is that the later
  ldconfig will link
	libGL.so -> libGL.so.100000 and thus always to the right one.

  How does your setup work when you do ldconfig? Does the ldconfig not
  link the libGL.so to the nvidia one because it has a higher version
  number?

  How are updates to the xserver-xorg-core and ... handled when running
  nvidia/intel at the moment?


I only want to help, and at the end have a nice script I would use, too ;-)

Best wishes

Norbert
