Holy crap awesome you are the best dude!

I asked about this awhile ago and I wish you had replied :D

I have boards without it so I would love to buy some if they are priced
lower than the official one - Do you have an estimate?

Might be a way for you to make a bit of extra cash as you could peddle
them to the various core/libreboot D8/D16 sellers plus leah/minifree,
the fsf, raptor (for integricloud x86) etc.

It is still quite important to have these boards as
propriatary-equivilant-functional for applications that don't yet run on
POWER (talos 2/blackbird) and this is a great step considering the D8
and many D16's even new don't come with that chip and they sell for IMO
too much on ebay. (my linky is $30 plus a silly $30 shipping for tiny
chip - so $60)
