[REQUEST] Lenovo ThinkPad Edge E520 Whitelist removal

I bought a new WLAN card for my laptop only to find out there is a whitelist..
New WiFi card: Intel Centrino Advanced-N 6230

I know there are older BIOS versions with the whitelist removed, but I would like to be up-to-date.

Model: Lenovo ThinkPad Edge E520
BIOS Version: 1.26
