This well could be - I use the linux-boundary recipe for 3.0.35+
(my board is nearly identical to a SabreLite from Boundary Devices)

I'm a bit confused by the '4.6.9p13' reference.  Is that part of
a GPU recipe version?  or a kernel version?

Can you point me to any discussion of this, or the kernel (which tree)
revision that made this change, etc?
