I've made a home for the disassembly at:

Will add comments to the 256 element shader shortly.

Most of the bits are making sense
- Control flow looks ok
- Uniform fetches look ok
- Data fetches via tmu0 look ok
- Floating point operations make sense

Its just the vpm read/write and rotator, and the movement of operands that need 
more work/understanding.
