Well the fact that they could also reproduce it on the CRB with UEFI and 
the latest firmware tells me it's most likely any system with this SoC 
and using S3 for suspend is affected.

I guess the same thing might be doable in coreboot ASL handlers for S3, 
but I don't know how well that would go over with coreboot folks.

They might say "It should be fixed in FSP" or "It's the kernel's problem".
