Well, they haven't so far. :-)

It doesn't, but removing the export was intentional, because that export 
is not needed for any in-the-tree modules any more.

In principle I can add the export back, but this function is supposed to 
be an internal ACPI interface and the NVidia driver is abusing it quite 
openly, so I'm not sure.  I guess I'll just send a patch for broader 
discussion.

Thanks,
