I just have to find it :)

Have you looked into the wlan calibration utility built into the driver. You can also customize the MAC Address.
Original source of info
I have used the calibartion utility once and copied the nvs_map.bin to all four of my kindles, only changing the mac address.
Manufacturer indicates that customer(amazon) should run uitility on each device.
We can probably find the original file by restoring to factory. I have looked in the factory update files and could not locate it. Of course it would be a custom file to each device (mac address unique).
My four kindles connected to secure wireless do not appear to have any problem.
I have also used my nvs_map.bin while running your ics build to retain my mac address.
I have reports from other cm7 users that running the calibaration routine and using resulting nvs_map.bin file fixes cpu scaling issue for them also
Thanks for your continued effort on this great platform.
