You don't even need bios to support turning off the nvidia card.. im
using a Asus N53SV-XR1
it has a nvidia optimus GT540M..
KMS works for the intel video card. so long as you dont use
packages... you have to compile xorg with
a few settings in your /etc/make.conf
as well as use the xorg intel driver, the vesa driver doesn't work and
will hard lock your system.

these settings go in /etc/make.conf
WITH_NEW_XORG=YES
WITH_KMS=YES


here is my xorg.conf

cat /etc/X11/xorg.conf
