Nvidia optimus KMS doesn't work

Hi all! I am on an HP Notebook with Nvidia Optimus. Displays are connected to the intel gpu, and I am using bumblebee+proprietary nvidia driver. The intel driver is i915.
Since the system is using the intel card to manage the screens, I though I could use KMS. But referring to this post on stack exchange:
http://superuser.com/questions/223094/h … ms-enabled
and also to the fact that plymouth doesn't work at boot (but strangely it works on shutdown) I found out that KMS does not work. Also, if i add "i915" to MODULES
in /etc/mkinitcpio.conf not only it still doesn't work, but also tty's do nothing. Gnome starts, but if I do CRTL+ALT+F2 or similars I only see a blinking underscore and no login screen. And if I try to write something nothing happens.
So the answer is:

If I use i915 as X gpu, but I have installed proprietary driver for use with Bumblebee, can I turn KMS on?
