I am seeing the same bug on current gutsy with Thinkpad X41 when using intel driver, the brightness jumps to highest setting when playing a video or when going to console etc. With i810 driver this does not happen. While I do not the same laptop as the original reporter, the graphics controller seems to be identical:
