The DQS values are stored in chipset S3 "NVRAM" during first boot, and used later when resume to fill them in. It could be done via simple backup of all mem cntrl regs but it is not done so.
I think this is a brilliant idea for improvement - it would also reduce the resume time ever so slightly. Either a structure for the chipset-specific registers that are needed, filled and saved at first boot and reused on resume - or a super simple blob copy of all registers. (If there's enough space?)
