I tried it on AOKP (7.12.2012 Build) and I can get past the "this device is not supported" stage and through to the Terms and Condition page but when I click agree, it tells me NFC needs to be enabled and "exit" "settings" menu option pops up. I click on settings which takes me to "more..." under settings which displays "airplane", "VPN", "tethering", etc but no NFC options.
If I remember correctly, on yesterdays release, NFC was there in all it's glory with the option for lockscreen, etc... But now, it's no where to be found.
I guess I'll be posting this to the AOKP forum (task650 and ktoonsez) and see what they say.
should be easy to get it working though...wallet works fine on cm9
