Should mini displayPort work with stock kernel & nouveau?

Hi,

I've just set up Arch on a MacBook 5,1 (nvidia GeForce 9400M & mini displayPort graphics output).

X11 works fine out of the box (stock kernel & xf86-video-nouveau). However, if I connect a external screen with a mini displayPort -> VGA adapter, the external screen only shows some vertical lines. I see the following error:

[drm] nouveau 0000:03:00.0: auxch DEFER too many times, bailing

Apparently, such a setup should work with the latest kernel (nouveau driver) and xf86 nouveau driver. In fact, some folks at RedHat report so with my very same hardware setup: https://bugzilla.redhat.com/show_bug.cgi?id=642728

Anyone has sucessfully setup a external monitor with Nouveau & mini displayPort?

Any help would be much appreciated, as this feature is critical for me.

For the record I'm using this from the core / extra repos:

- Kernel 3.1.5-1
- xf86-video-nouveau 0.0.16_git20110829-1
