Macbook Air 2017 (7,2) Support

Getting a graphical desktop out of FreeBSD took surprisingly more work
than with Dragonfly, but I've at least confirmed I'm seeing the same
problem on FreeBSD 12.1. Useful exercise as I also noticed the phantom
clicks happen on the console of the 5.8.1 install media (and a clean
installed system).

Incidentally - apologies if this email pops up twice. All the moving
between systems has made it difficult to keep track of my mail client

only to give me a way to rule out anything DragonFly.
