The FCC-mandated radiation testing for FM receivers is absolutely trivial compared to all the other emissions tests required by them for electronics devices, especially intentional radiators such as mobile phones. They're at the lowest tier of assessment and authorization, which doesn't even require the use of an accredited testing laboratory or filing any kind of application or registration: http://www.ecfr.gov/cgi-bin/text-idx?SID=df5370d2e0e33e10c9b55ce593b56af3&mc=true&tpl=/ecfrbrowse/Title47/47tab_02.tpl http://www.ecfr.gov/cgi-bin/text-idx?SID=df5370d2e0e33e10c9b... Any company capable of making a mobile phone should have the equipment to do this in-house. Now, it's entirely possible that the chipset manufacturers are charging licensing fees to enable FM radio, but as far as I can tell companies don't have to pay a single cent to the FCC for this.
