In the next days, probably today, I'm going to update my Debian Unstable 
to use Linux 3.8 (thanks to experimental branch and pinning).

What I wanted to mention is that I had sent an email to Seth Forsee (the 
patchset developer that you mentioned) and he told me that:

* He doesn't know if the patchset would work in my model because he was 
never able to test it in my model (MBP 6,2)
* Depending of the behaviour of my firmware I might not need any patches 
because some older models were reported to work with 3.6.
* I might need to use nouveau instead of nvidia propietary driver for 
switching to work.
* The patches, which was never accepted upstream because it was kind of 
a last resort can be found at: 
https://patchwork.kernel.org/patch/1429901/ (I just save it here so that 
if vanilla kernel doesn't do the trick I would try them).


I'll keep you informed about what happens with my updated Debian and I 
will probably document it somewhere.
