In the context of the code currently in sound-unstable, I'm not sure.  At
the time it was committed the setting of add_out_jack_modes was certainly
useful since having access to that control is definitely needed on this
model given that line out and headphone share a physical jack.  Whether it's
still necessary to explicitly turn on the HP amp of node 0x10 given
Takashi's latest changes I'm not sure.  I suspect it is.

To summarise: I expect this patch is still relevant.  However, I will try to
explicitly check this and let you know.
