For anybody who is interested, I've collated shader dumps from all of the tests (bar the batch tests) from 3DMark06:
http://www.neeyik.info/fmark/06shaders.rar
Each folder in the rar file contains the vertex and pixel shaders from the respective tests, as caught by 3DAnalyze. The SM2.0 and HDR folders contain quite a lot of shaders because in the case of the SM2.0 tests, I ran them twice: default and then without HW DST. The same applies for the HDR tests but this time default and then with software FP filtering.
A quick glance at some of the longer pixel shaders in the HDR tests shows that a couple of them are using if not equal to...else with a bucket load of instructions that can be skipped; the shader particle test is also using flow control in its vertex shader that performs the vertex texturing. Oh and the Perlin noise test is also one hell of a PS!
