OLPC XO 1.75 GPU question

[Jonathan Wilson]

I read about the OLPC XO 1.75 including a new ARM SOC from Marvell.
 From what I read, this SOC includes a 3D GPU and a hardware video decode 
engine.

What is the plan regarding support for these components in the OLPC XO 1.75 
software and how does that fit with the general "100% open wherever 
possible" philosophy of OLPC?

Will support come from a binary blob or from an open source driver (or will 
it be like the wireless firmware on the current OLPC whereby its supported 
by a binary blob initially with people who haven't signed any NDA 
contributing to a reverse engineered replacement for said blob as a 
community project?)

Or will the XO 1.75 not support 3D at all? (which would presumably save 
power and make the battery last longer)

I am curious because this is the first device with ARM and a 3D GPU that I 
know of that is being made by an organization where openness is a stated 
goal of the project and (on the surface) that seems to conflict with the 
highly proprietary nature of most vendors in the ARM SOC space.
