G?bor,

I just pulled the card, and it's not the chip you mention.  It's a 
"BCM94312HMG"  (Notice that it doesn't have the "B" at the end.  I would 
assume that indicates the Bluetooth integration.)

I've taken few photos of the front and back of the card.  Let me know if 
you want to see them... I can post 'em on my website or flickr for your 
viewing pleasure.

Thanks,
John Daiker
