I think this is actually an issue with the -intel X driver, which pokes the chipset backlight registers directly and overrides the platform legacy backlight controller. Still, I suspect that the best approach to handling the backlight stuff on new Thinkpads is just to leave it up to the video extension. Just check if _BCL, _BCM and _BQC are implemented and then refuse to create the backlight? -- Matthew Garrett | [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
