On some device like the i945 Thinkpads, connecting an audio cable in the output jack plug works, so you can record a clean signal by doing that and by messing with the sound volume buttons before re-booting. I've tried that on a gm45 Thinkpad also with coreboot, and I wasn't able to redirect the sound. Denis.
