Binary package hint: xserver-xorg-video-intel

On Ubuntu Jaunty Alpha3 with all the latest updates(28.1.2009) the xorg freezes when starting, only when the system is running a kernel with the option CONFIG_HIGHMEM64G enabled.
This has been experienced on thinkpad x300 with 4GB of memory, with a GM965/GL960 graphics controller.

I firstly experienced this problem when i tried the linux-server kernel. The system boots fine, but when i start X then the graphics completely freeze. I am able to reboot the machine with alt-ctrl-delete, although nothing is shown on the screen until it resets.
The same system with the linux-generic kernel works fine.

I recompiled the kernel shipped with jaunty, using the linux-generic config file and changing only the kernel support to be for 64GB of memory CONFIG_HIGHMEM64G=y. The result was the exactly the same like using the linux-server kernel. The graphics freeze but the computer can be rebooted.
