Graphics on MacBook Pro retina 10.1

-- Firstly I would just like to mention that openSUSE 13.1 runs without any major problems out of the box using GRUB2 and UEFI on a MacBook
-- Thanks to everyone that worked hard on this.

The laptop display and HDMI port works, but I'd like to enable the following;

• Switch between integrated and discreet display
• Use a Mini DisplayPort with an external screen

I tried plugging in a MDP adapter at various stages.
Before boot, login screen does not show, after login, display locks up (Caps and Num Lock still responds)
In single user mode I can see that the Mini DisplayPort adapter is detected in /sys/class/drm/card0-DP-1/status

After some digging through the logs it turns out it's the nouveau driver that breaks when the MDP is plugged.

I was planning on installing Bumblebee (http://en.opensuse.org/SDB:NVIDIA_Bumblebee) hoping that it resolves the problem, but apparently Apple doesn't use the NVIDIA Optimus technology. I'm not sure if Bumblebee will fix it or worsen it.

I tried vgaswitcheroo to switch between the display cards using
echo <switcheroo_command> > /sys/kernel/debug/vgaswitcheroo/switch
but most of them either do nothing (except for OFF) or lock up the display.

Does anybody have any suggestions or experience with this?

Some system information:

cat /etc/os-release
lspci -nnk | grep VGA -A2
ls -la /sys/class/drm/card?
ls /sys/class/drm/*/status | xargs -I {} -i bash -c "echo -n {}: ; cat {}"
cat /sys/kernel/debug/vgaswitcheroo/switch
Some dmidecode info
zypper search -s nouveau
zypper search -s intel
Thanks in advance
