Just checked, it was Michael Jerz at the My-Symbian blog who said it was the same as the i8910, since he actually has the N900 to hand seems like a reasonably trust-worthy source.

Wait it does not support that officially as it can't do 802.11 b/g/n at all? Or that it can with hackery?

From my understanding if the N900 has the Navilink 6.0 chip then it should support 802.11 b/g/n.

The official spec is 802.11 b/g.

How much more power does 802.11 n consume compared to 802.11 b/g ? Is that even an issue ?

But the TI link in the first post doesn't. Maybe "supports" in the sense of

optimized to ensure seamless coexistence between GPS, Bluetooth, FM, WLAN and cellular functions.

Ah, shame that it wouldn't support n speeds. Would be nice to have some future-proofing. Though I guess even with n speeds there would still be bottlenecks somewhere.

There are at least 2 chips listed in the kernel for most functionality (camera, WiFi, FM, etc.). Either the chips they've been using on the prototypes have been changing or they're working on multiple devices (or both).

We'll probably have something out of the Summit.

Yes please I am waiting for that to complete the Wikipedia article.

FM RX is supported, but not officially....

The Bluetooth chip is a BCM2048, and it supports FM RX. The kernel source clearly says so. :)

Are there details on what the sample rate is and if it can be changed for more precision?
