Awesome, thanks guys.  It's working great on the 9560 on my ThinkPad 
X1C7.  A speed test showed 44/18 Mbps and it continues to work fine 
after an S3 cycle.

The firmware version string looks odd:

iwm0 at pci0 dev 20 function 3 "Intel Dual Band Wireless AC 9560" rev 0x11, msi
iwm0: hw rev 0x310, fw ver 34.-1169155311.0, address 90:78:41:39:57:8d
