OK

I'll push this patch to Linus for -rc5 then without the revert of commit
commit efaa14c.  That's all I'm going to do for 3.11 in the ACPI video
area at this point.

As far as the blacklisting is concerned, I still have the blacklist of
your Asus machine queued up for 3.12.  Since you're claiming that it
doesn't have any side effects on that machine, I think I can apply it.

However, for other machines to be added to that blacklist I need to see
requests from their users with confirmation that there are no visible side
effects there.

I think this is fair enough.

Thanks,
Rafael
