As further clarification. The GPU runs what you'd consider a graphics driver on an RTOS (threadX). The application processor running linux then sends commands to the GPU much like an application would send commands to the OGL driver.
Things that require direct access to the hardware like OpenCL, or even X acceleration (Render) cannot be done (without broadcom offering updated firmware).
Objectively, it is quite an interesting encapsulation, but ultimately a useless one if you want access to the hardware. Ultimately, the Rpi foundation was mischaracterising the open nature of their driver.
