I also think it seems a good idea. 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.
