Before I try this, may I ask if anybody *on this list* has gotten the
following working?
http://askubuntu.com/questions/264247/proprietary-nvidia-drivers-with-efi-on-mac-to-prevent-overheating/613573#613573
I've got a 6,2, not a 7,1.
Yes, yes, “Don't use a Mac” or “Don't use the proprietary driver”, but
just because I have underwhelming hardware doesn't mean I wish to
capriciously toss it for something better. I also haven't figured out
how to use only the integrated GPU (didn't work last I checked), nor
does nouveau perform well enough for games.
I only found the post on a Ubuntu-related website. I run Arch. I see
hints of dual GPUs working given a very recently pulled kernel commit.

apple-gmux: Assign apple_gmux_data before registering
Registering the handler after both GPUs will trigger a DDC switch for
connector reprobing. This will oops if apple_gmux_data hasn't already
been assigned. Reorder the code to do that.
