i915 KMS causes hang on bootup; Thinkpad x40

[Sam Thursfield]

I've been tracking the Karmic alpha. In the past couple of days, an update broke the boot and now the laptop hangs at a black screen.

Adding 'i915.modeset=0' to the kernel command line fixes the problem. So it could perhaps be a KMS issue :)
