To get suspend working properly you must do the following:

Add disable_mode=1 to your kernel boot options.
In my case I use grub so I appended this to GRUB_CMDLINE_LINUX
in /etc/default/grub and then ran the following command as root:
grub-mkconfig -o /boot/grub/grub.cfg

Install rc-local from the AUR and add the following to /etc/rc.local:
awk '$3 ~ "enabled" {print $1}' /proc/acpi/wakeup | xargs -I{} echo "{}" > /proc/acpi/wakeup
echo LID0 > /proc/acpi/wakeup

@crencom I have been actively working on getting this up to date with 4.9 -- I've ported over all the files, hooks and configs from the base kernel since it went from testing to base but I haven't cracked it yet. I'm hoping to get something working in a few days tho, getting super close.

I have the 2015 MBPr 11,5 and have successfully installed this kernel version. Has anyone attempted to build a newer kernel version - 4.9, 4.10? I am trying to build the 4.9.6, but am erroring out at the PCI Quirk driver. Which seems to be related to the poweroff quirk patch. Any ideas?

People who experience regular freezes, have you found a solution ?
I get myself freezes, especially when watching videos on youtube or netflix.

@jjhoughton - In retrospect that should've been obvious. Thanks for your help! I can confirm that on a 2015 MacBook Pro this allows you to control the screen backlight with gmux_backlight.

@crobbins You just install it using pacman
sudo pacman -U linux-macbook-4.8.16-1-x86_64.pkg.tar.xz linux-macbook-headers-4.8.16-1-x86_64.pkg.tar.xz

and then just add an entry in grub as you said. You should see these two files in your boot directory initramfs-linux-macbook.img vmlinuz-linux-macbook the first being your initrd and the second the kernel.

I used makepkg to build linux-macbook, but it's not clear how to actually install and configure it. I can add a boot entry in GRUB, and I see stuff in the pkg dir, but I doubt I'm supposed to just copy the files around manually. How do you properly install this package?

To ignore PGP signature errors with yaourt use:

yaourt --m-arg "--skippgpcheck" -S linux-macbook

To get rid of the signature verification errors, add the --skippgpcheck parameter to makepkg:

$ makepkg --skippgpcheck --si

Even after adding keys as suggested per @m3thodic I am still getting signature verification errors and failed builds. Running on Macbook Pro 11,5, Latest install. Any suggestions? Thank you!
