Those will only go to the pads for the PCI-e card connector in the upper left of your photo.
And since you don't have a 3G, PW-3 (neither do I), then we can't use AT commands to see if we can access it from the Kindle (through the modem/radio).

Is it a hardware or software limitation? Does the firmware package have a flag within to determine modem usage or would it just be missing altogether?

Now that is quite interesting. Solid State PCI-e storage would be nice. Are those two lines individual PCI-e connections?
As for the 8 pins on the sim pinout I have found the identical layout on my revision.
