I am happily using chinook on my n810 and don't feel the urge for starting over. My tablet is optimized for my needs, and, frankly, I am sure it would take forever to remind all the hacks I applied and transfer them to a reflashed instance. Plus, I installed diablo to my other tablet (n800 - I am plainly unable to resell these toys :-) and can't see any compelling reason for the transition.
I'm sure there are other guys out there who did like me.

So, I would be much grateful if you could backport streamtuner - of course if it isn't too much fussy for you (i.e. installing again the chinook toolchain or the so).
