(Firstly, I've just now joined the xorg list, so I couldn't see the CCs from 
the archived copy of the announcement, and I duly apologise if I've dropped 

I have a problem with the xf86-video-intel-2.0.0 driver (hand built) running 
under Debian unstable (Xorg server 1.3.0). The machine is a Core 2 generation 
Macbook with what I believe is GMA 950 video.

Normally, the driver works fine. But I've recently been trying to set up 
multiple monitors (laptop panel + VGA display) without success. Merged/clone, 
it seems to work fine, but if I try to enable the Xinerama extension, the 
server crashes.


"xorg.conf" is my current, working config. With this config, I 
get "Xorg.0.log-good" from the server. Uncommenting this line:

#	Option		"Xinerama"

Is enough to give me the crash, and the resulting "Xorg.0.log-bad".

It's obviously possible that my config is somehow incorrect, but it looks more 
likely that this is a bug in the intel video driver:
