I forgot to mention the BIOS feature. if you can disable the Intel
integrated graphics via BIOS you solved your problem, otherwise, you can't.
I've a laptop with optimus too, and BIOS hasn't the Switch-Off feature
(ASUS U46SV), so I've patched BSD9 and I'm using the intel GT on BSD.
Otherwise, Linux + bumbelbee works quite good.
In my spare time, I want to port the bbswitch driver (from Linux) to
switch off the NVidia graphic chip, that eats tons of Watt...
BUT, there's no software way to use NVidia chip as "primary" VGA without
switching off the Intel integrated graphic.
PS the pciconf shows a strange values also on Linux (lspci), BUT using
Xorg log shows the correct graphic driver. I guess the pciconf shows the
"optimus" device, rather then the raw graphic chip.
