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.
