One option is to put it on the connector but provide some mechanism for
userspace to define the relationship between platform/firmware
interfaces and connectors. We ought to be able to tie connectors into
the ACPI namespace and do a better job than we currently do with the
association between backlight and connector. The bigger problem is
figuring out how platform interfaces tie into things, and that's where
heuristics are probably going to be involved.
