This what it looks like for me:

N900 Board: Noxia RX-51 board
N900 Board Ver: 2101
Processor Information: ARMv7 Processor rev 3(v7l)

Yes, the processor information is "v7l" and not "v71". At least that character looks more like an "l" than a "1".

Smooth keys or the rough texture feel?
I really cannot tell. Since this is the only N900 I have ever seen in real life, I dunno which it is.

I bought it in February as used, AFAIK it was bought as new back in December.
