I don't really know. The backlight / backlight_legacy seems to have been introduced in 2.6.18. Before that, I guess only "legacy" (ioctl) was present, so no need of a .config option. Some people don't even need pbbuttonsd to adjust lcd backlight. I guess a couple of #ifdef could adjust pbbuttonsd behavior, so if ioctl aren't present, use sysfs. But currently, if you switch to 2.6.18, I guess you won't be able (at all) to adjust backlight because CONFIG_PMAC_BACKLIGHT_LEGACY is not set on debian kernel (see #389693). -- Yves-Alexis -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
