I'll try to make a new patch using your suggestion. BTW, I have one question about disabling backlight interface. My toshiba laptop has three sysfs backlight interfaces, "acpi_video0", "intel_backlight" and "toshiba". Fedora16 is always using "acpi_video0" interface. If I add acpi_backlight=vendor in boot param, then Fedora16 uses "intel_backlight". # "toshiba" is lowest priority. So I want to know how to disable "intel_backlight" interface. Or enable "toshiba" interface only.
