Two things:

1) This is an NVIDIA-style driver release.  You will only find wrappers
around binary-only proprietary drivers, and no actual source code for the
2D/3D components of the Kyro/KyroII.  They only "open sourced" their kernel
compatibility layer.

2) Kyro/KyroII - this is _not_ the chip used in the Dreamcast, you may be
able to consider it a "superset", but any source for the Kyro series
(PowerVR3 and beyond) won't do any good for the Dreamcast.

Your best bet for low-level specs on the PowerVR2 found in the Dreamcast is
to reference the documents written by other homebrew DC developers.
