dmesg with drm.debug=0xe

Linux boots, but display 'fails' when i915 KMS kicks in. Console input is
possible, and system is useable via ssh; X can be launched from console.

'Fails': on tested 2.6 and 3.2 kernels, the entire screen is taken over by a
colourful snowstorm. On 3.8.4, the snowstorm flashes briefly then the screen
blanks; disconnecting and reconnecting the display again yields a colourful
snowstorm. Launching X will also transform the black screen into a snowstorm.

I've tried with built-in i915 (fails on transition from initrd), loadable
module (fails when i915 loads), and with i915 in initrd (fails immediately).

The system is a Acer Revo RL80, which has only DVI-I output. The display is a
projector with native resolution 1024x576.

With KMS disabled in the kernel, the failure doesn't occur; but i915 cannot be
used for X.</pre>
