Hi Alban/list,

	In case you missed it, I created an upstart script at:

http://www.voip-x.co.uk/files/adam/upstart-vaioz-gfx.tar.bz2

	This does pretty much the sort of thing that your modified script does, 
though it specifically saves and restores either the standard or NVidia gl 
related files ( that it needs to. ) It also tried to determine which files are 
currently on the system so if, for example, you update using apt-get or 
whatever whilst using the NVidia card, the new system files will get saved as 
Intel ones and restored next time you boot in stamina mode. You still need to 
boot an old kernel every time you want to use the NVidia card though ( or hack 
the BIOS. )

	The other advantage is that you can add "and started vaioz-gfx-config" to 
the startup dependency list for the display manager ( /etc/init/[gk]dm.conf ) 
which prevents the need to restart the display manager.

Adam.
