Quick reply...
I am reading FM receiver code.
http://mxr.maemo.org/fremantle/sourc...adio-bcm2048.c

Correct me if I'm wrong.

It has function bcm2048_set_region
It is called only once, during bcm2048_probe (driver loading?)
It sets region to BCM2048_DEFAULT_REGION
It is 0x02 .
Region 2 is Europe, channel_spacing 10, bottom_frequency 87.5, top_frequency 108, deemphasis 50.

Therefore, Nokia has written the driver without any way to check the region during loading of the drivers. Hard-coded to Europe.

I will be glad if somebody proves me wrong.
