 the priority is to test the hardware.  whatever works that allows
that to happen, in the fastest possible time, is what will be used.
it's a different set of priorities, arokux.

 reach the goal in the fastest time possible, flow round problems and
get it done.  there's no driving force to stick to 3.4 for the sake of
sticking to 3.4, as part of achieving the immediate goal of testing
the hardware.

 it's a different rationale, arokux.  in achieving a specific goal
there is no loyalty to "switch" or "stick".  there is absolutely no
loyalty to the 3.3-dev code either.  in the space of just 2 weeks,
collectively we've tried cubieboard2-3.4-dev, sunxi-3.4,
cubieboard2-3.3-dev - the list goes on and on.

 each has their own flaws and between them it's been possible to get
the goal achieved: test and verify all hardware interfaces as working.

 quotes sticking quotes with a specific kernel release just for the
sake of it does not actually help achieve the goal: in fact it
massively hinders it.
