A way to switch off nVidia discrete cards ?

[Florent Peterschmitt]

Hi,

I've absolutely no skill in system development but I think, based on 
bbswitch (which is part of bumblebee project), that doing such a think 
would not be too difficult.

I have a 9.1-RELEASE FreeBSD which I'm going to upgrade to -current, for 
testing and developing purpose so, is there any documentation or little 
how-to of how to develop for FreeBSD, in the kernel, using access to 
hardware and ACPI ?

Thanks
