[coreboot] X220 Wifi Suspend

I recently flashed my Lenovo ThinkPad X220 with Coreboot and a SeaBIOS
payload. I made an attempt to document the whole process.
Initially, everything seemed to work fine. I was able to boot to SeaBIOS
which handed off to a Debian testing install (Stretch).
Now that I've used this laptop a bit, I realized that wifi appears
hardware-blocked after returning from suspend. I've found lots of pages
online with "one weird trick" to fix this, and have tried many of those
tricks to no avail :(
I've tried a couple of different Coreboot configs neither of which
made any difference. After re-flashing the old proprietary ThinkPad BIOS
wifi comes back from suspend just fine.
I've tried both the standard intel wifi card and a card from
ThinkPenguin that uses the ath9k driver using the coreboot config.
Any help or pointers anyone could give me would be much appreciated!
