Am I crazy or does the N800 have an FM radio in it?

/sys/devices/platform/i2c_omap.2/i2c-0/0-0010 # cat name

Nope.

radio-tea5761.c is a real driver as far as I can tell. It
lives in
drivers/media/radio in the 2.6.18-osso29 source code from
maemo.org.

Somehow I don't see easter eggs in the kernel as an
acceptable
practice. 

The question is whether or not it's wired in and
functional.

Is this a TI chip? I know TI has some bluetooth/FM tuner dual purpose chips [1]. Maybe this is related? I doubt the antenna is hooked up, though, but maybe it shares the antenna with the BT and we can just have one or the other operating...

Andrew,

actually what I mean is easter eggs in the hardware, waiting to be discovered.

I'm betting on the NXP BGB260FM [1]. I took your lead, then did some googling. It's a combined Bluetooth and FM stereo on a chip, but uses the TEA5671 as it's FM component. From the block diagram it has seems to have separate antenna inputs, so I'd assume it's not connected. Or maybe the quality is just lower than that cheap camera so Nokia left it disabled ;)

A user suggests it is:

uary/003605.html

However, I can't see an "fm-radio" app in the
Opened Hand repo from
looking at Packages.gz.

Cheers,

Andrew

Um, I dont know where this confusion is coming from, but we
at OH have
never written an app called fm-radio (or even heard of one).
We know
nothing about the radio. Sorry :(

Nokia JUST released an application that activates an FM
radio chip in 
the unit.

No, this isn't an April Fools - I'm listening to FM radio on
my N800 
right now.

The application plugs into the desktop, so you have to
activate it on 
the desktop rather than from the application menu.

Nokia really kept that one under their hats - kudos.

What's the license and where can I get it?
